ActionScript 2.0 :: XML Attribute Doesn't Stay On Each Object Of The Loop

i'm working on a gallery that loads thumbnails from an xml file into 3 columns and when you click on a thumbnail it opens a new window with the fullsized image in.

I have modified code from a gallery tutorial to load the thumbnails from a xml file. They are going in 3 columns at the moment (I don't understand why but they are) but only the last image has a hand cursor when you rollover it, and then when you click on it, it traces "undefined" into the output box.

I have put

Code:

trace(images_arr[i].attributes.fullsize);

just below the bit where it loads the thumbnails and it traces the right path from the xml file for each image.

get it to trace the right path from the xml file when you click on ALL the thumbnails, not just the last one.

Code:
function GenerateThumbs() {
images_arr = images_xml.firstChild.childNodes;
gap = 10;

[Code]...
