As far as I know, what I ask here isn't possible, but I thought I'd ask anyway in case I'm missing something.
Suppose you want to let users upload JPG images, and these images are scaled into smaller icons and the original images are always discarded and never required again. Is there any way that would commonly work in most modern browsers that would let the user select a single image on their hard drive, have that LOCALLY turned into a thumbnail and upload the created thumbnail to a server?
In a case where the server just needs a small image, it would be wasteful both in user time and server resources to proceed uploading the whole image, only to immediately discard it. It would be much better to just scale it on the client.
I can imagine three options. Just plain HTML/Javascript, using Flash or using Java. If this were possible with Flash, that would seem like the best option. But reading flash.net.FileReference documentation, it seems that you can upload a file from the HD yes, but you cannot look inside the file you are uploading. On the other hand, if you enable "can access local files" in Flash publishing options, it seems that you can then no longer access the net, so that doesn't work.
With HTML/Javascript, it is possible to load images and display them on a <canvas>, but if you try to access the pixels of these images, you get security violations, so that doesn't seem to work.
Java I hesitate to use, because only 96.52% of my users have it installed, and the file upload dialogs I have seen implemented in Java (at Facebook for example) have not worked well (unresponsive interface). I wonder though if Java is the only thing allowing resizing images from local HD?

I coded a multiple file uploader using the FileReferenceList and PHP. It works great for me all the time on my Fios internet connection, which is by far faster then DSL, etc... So my issue kinda went unnoticed until I got on a DSL connection. Now, many of the files I was uploading seem to be timing out, but there is no indication of this. No errors, etc... just stops its progress and NEVER finishes. Tried bumping up the script execution time on the server

Intro:I started a flash-based website a few years ago. Back in 2006 I was able to get a xml scrolling thumbnail, image loader to work without a glitch.For numerous reasons I had to put the project on hold until now. [one was that my 30 day trial of flash expired and only recently was I able to purchase the Adobe Web Suite CS4 as well as a new computer which could run the apps.]
Last Friday saw a bump in the road in the development of my site as two, rather straightforward task, turned into something short of a nightmare as I have been unable to get past these two, seemingly, relatively simple task.I have posted in 4 other flash forums the issues, in detail, that I am facing - and have quite a bit of interest/views in the topic as the numbers suggest - yet no response/answer as of yet. [Which confirms other messages I have seen which seem to state that working with buttons has become increasingly difficult with the newer version of flash - something Im a bit surprised with actually from Adobe. - I would have thought there would be a palette where you could set parameters...]
Screenshot of Site/Timeline: Before getting into the two questions I have, I would like to post an image of the site as it looks whenever an swf file is saved out, as well as a piece of the timeline in the back for reference.As of now when the swf file is saved out you get exactly what you see above:
a: A scrolling thumbnail
b: ...which loads a large image when clicked on it - PEFECT...
BUT...1a: I need for the buttons to load in this action, not for it to just load on its own.[i.e., the silk_paintings gallery is what is open, so I need the "silk_paintings" button to call up this action]
note: Initially I had attacked this problem by taking out the actions layer you see above and applying it directly to the individual buttons with some crude MouseEvent Listener/Handerls... that did not work - at all.Im sure it may be "easier" to make an array out of it, but with my coding level it may be "easier" to apply it to the buttons.
1b: How I currently see it, I would take the xml-list and duplicate it for the number of galleries I have.[I would then re-name the xml-list to reflect the name of the galleries they are to represent, i.e. "silk_paintings"][also, I would have to rename the folders to "thumbnails1,2,3, etc., & "images 1,2,3, etc"
From there I would duplicate the actions and paste it into the buttons, changing the xml-list name to that of "silk_paintings", etc., as well as write in the MouseEvent listener Handler to make it work. [ah, ha, but what is that magic phrase, I have tried to implement various code from other tutorials, and all in vein.]
At this point I would be tickled pink just to get this to basic function to work.However, once the buttons are working and calling up the xml, etc., then I need the buttons to stay on the semi-transparent blue color it is whenever in the 'hit' state. [note: NOT pictured above.]With the way the buttons are currently set up, and with wanting to use scripting to get them to interact with the thumbnail gallery, it will have to be some miraculous code to tell that button what color to stay as whenever its clicked, and of course it going back to white when another button is clicked.
Conclusion:Since this is an Adobe Forum I would like to make a few additional statements in hopes that the developers, etc. may take heed.Adobes products are not cheap, and when I went to purchase the websuite I went in as a designer needing a program as not to need to program.I understand the flexibility that coding gives, but something as simple as linking buttons should not be in the realms of rocket science.

I am trying to create a web site suing adobe Dreamweaver and flash, for the first time.I am trying to upload a webpage that contains swf.When I check mu site I could only see a blank page with the webpage title at the top of the page.When I contacted the webhosting company they say they can see the message that a newer version of adobe flash player is required. From my computer I cannot even see the message.The helpdesk person said there are possibly two reasons for it. Either there is a problem with the code in flash or it is too large.Are they too large to upload? If so, what is the maximum size of file can I upload on a webpage?I know they are basic questions but I am trying to create website on my own.

What are, nowadays, the best practices for uploading a large file (which may cause a timeout) with ASP.NET Web Forms and/or MVC? Increase Server.ScriptTimeout (only for the specific POST request); Use some flash client-side uploader like swfupload ([URL]) or plupload ([URL]), but Flash uploads have some issues with proxies; Use some gmail-like javascript (like [URL]

I am loading the swf of this scroll bar into my main project using a button. How do I make a large version of the thumbnail load above the scroll bar?
Here is the code that is on the main timeline:

//Save the width of the whole galleryvar galleryWidth:Number = infiniteGallery.width;

I recently added a loader page ("loader.swf") to my flash website. Basically, I created a new file and added a loader which shows the percent loaded, and then it loads in the "index.swf" file. My question is: when I upload my site to the web server, do I use the loader page as the "index" page? My dilemma about that is that I don't want the URL to read "[URL]"...

I have some pretty large PNG images stored in a database (example 1000x15000 px, 4.5MB). I am trying to load this using the Loader class...the problem I am having is when I call load(), nothing happens. No events, no errors.I can take the same image and embed it. As long as as I set the height to less than 8000px it works fine. If I convert the embedded image to a ByteArray and try to load it, nothing happens.

I have set up an xml thumbnail gallery using some of the great tuts on this site (I'm a designer so this dev stuff tends to get a little confusing). Basic setup is quite simple:
xml holds titles, thumb urls and details set up thumbs as a grid system, so they're loading in as columns, all of which is working great.
I have run into a bit of a brick wall though, and that is how to get the thumbs to sequentially load in, instead of random as they currently are.
Code:
...
function GeneratePortfolio(portfolio_xml) {
var portfolioTitle = portfolio_xml.childNodes[0].attributes.title;
var rootUrl = portfolio_xml.childNodes[0].childNodes[0].attributes.rooturl;

I have found out that I can not use loaderInfo.getBytesLoaded in as3. I have a gallery located here: [URL]the functionality is almost complete, but my gallery still has issues loading all the thumbnails. It seems that sometimes they wont load while sometimes they do. I have split my thumbnail process into:
LoadThumbs: Loads the thumbs
Callthumbs:Arranges the thumbs
Each function is called once per thumbnail. My problem is that I can not find the bytes loaded information for the thumbnail as it loads. Event completion and preloaders dont seem to help. I doubt it's my alpha tween because the thumbs are un click-able when they are not there. This is the info for my function, with the comments indicating the parts that bring up errors.
Code:
function loadThumbs()
{
x_counter = 0;
y_counter = 0;
[code]...
How do I get the loaded info of each thumb as it loads? Do i need to make a new class file?

I have a sliding thumbnail gallery which when a thumbnail is clicked loads an external .png into a container with an instance name of mycontainer which I have on the stage in the .fla. Its added like such:
When the Loader's (which I gave an instance name of imgLoader) complete event is called the function onLoaded loads it -like this: mycontainer.addChild(imgLoader);
I also added a mask(stageMask2) to mycontainer which is the same size as the external .png--I then used this code imgLoader.mask=stageMask2; to mask the .png. I did this because I added a zoommc function which enlarges the imgLoader and wanted to keep the visible size of the container the same. I would also like to be able to drag the zoomed image. I don't want to drag mycontainer as it contains the mask and I cant drag the imgLoader as it doesn't have that property--Do I need to put the imgLoader in another container?
Here's the problematic code:
var stageMask2:Sprite = new Sprite();
stageMask2.graphics.beginFill(0x183045,0);
stageMask2.graphics.drawRect(swfX,swfY,604,403);
stageMask2.graphics.endFill();
var closeWin:TextField=new TextField();

I'm looking to do a sliding image menu like this one: [URL]. I can do this using tweening but it is not as smooth as using actionscript. Does anyone know what the name of this is as when I do a search as I can't find any solutions? I've tried 'thumbnail expand' and 'image easing' but am not getting any hits.

I have found an excellent tutorial and source file for a 3D image gallery. However I would like to make the thumbnail click thorugh to a url link when pressed rather than loading the image into the gallery.
Currently the images load in through actionscript. Is there a way to amend this script so you can specify that a thumbnail clicked links through to a url, like you would with a normal button instance rather than loading the image.

I asked a similar question before but didnt get a definite answer! Basically I just want to know if its possible to have a standalone SWF file which allows the user to browse there computer and load an image into the SWF to view it (in AS2)? Ive researched this FileReference class but it seems that requires servers and what not. I only want to upload the image to the SWF, not to an external server?

For the past few hours I've been trying to figure out a way to add a watermark to an image file before uploading it using the FileReference.upload(); method. The uploading works already. I just have to figure out how to get a small watermark (PNG image with alpha-transparency) on the lower right of the image file. Another thing is, I don't want to modify the source file. I just want to add the watermark on upload.
What approach would you recommend for this type of setup? I also can't seem to find any pre-made classes already that I can use for this certain thing. Is this not a very common task? And no I can't use server-side (PHP) to do the watermarking because I'm communicating directly to a service's API, not through my server.

I am writing an app for android devices, it uses the CameraRoll class to retreive images from the gallery. It then catches the raw bytearray data and encodes it into a base64 string, then sends the string via httppost to a server that decodes the string and saves the file.Every part of this is fine except one detail, the images are corrupt when they are saved on the server. Except one thing that makes things weirder, when I load these corrupt jpg images into a flash app they work just fine.Previously I have made apps that uses the Camera class to take photos in the app, and this works fine, the reason I am using cameraroll is because I want to be able to get high quality images, which is not possible using the regular camera -> bitmapdata.draw -> jpegencode -> send method.The code is basically thi

but i want to upload file without using FileReference Class i am using File Class on Air 1.0 on Flash, and that class can provide full url of image from my HDD like: D:My Documentsimage01.jpg
there is any way to upload this file on my HDD to server without using browse() class for selecting file on Flash with PHP?
or is there one way to convert File Class (AIR) to FileReference?

I need to upload an image to a SWF, however I can't use ActionScript for it because the client wants drag-and-drop capability. I figure that I can make the upload button cause a popup, where there is JavaScript for drag-and-drop. The SWF allows for some photo manipulation, so the image needs to be uploaded, and be in the SWF for that use. how can I make that image accessible to the SWF file?

I've developed a Flash quiz app for facebook, which calls for a php script silently upon completion. The php script's function is to generate an image from the POST data sent by the flash, and then post it to the user's wall.That would be all neat and dandy, but for some reason the image never gets uploaded, probably because when i call it, it's like [URL] and the facebook SDK script inside gets an Oauth error, probably because it is not embedded in their canvas.
If I'd like to have my php script generate an image and upload it to the fb wall, then how should I call it from the flash?This is the AS2 code I'm using currently:
callRemoteFile = function(ourVariable:Number) {
var result_lv:LoadVars = new LoadVars();
result_lv.onLoad = function(success:Boolean) {
[code]....
If I simply navigate to the php with my browser it giver me this:
Fatal error: Uncaught OAuthException: Invalid OAuth access token signature. thrown in /home/a01223445/public_html/appfolder/base_facebook.php on line 1039
If I view the same php through facebook canvas it works perfectly. My problem is: The canvas will show the flash and I want the php to silently be evaluated while the flash is running.
