ActionScript 3.0 :: Make An Image Gallery That Uses A Carousel Style Animation?

I need to make an image gallery that uses a carousel style animation...minus the 3D part.Basically, we'll have an array of images loaded from an XML file...could be any number of images.The stage will have 5 images lined up edge to edge. Each image will be 300x200, but masked to only show the middle 100x200 pixels. The image in the middle (the third one) will be fully visible, with the mask showing all 300x200 pixels of the image.When the user clicks on the next or previous buttons, the entire row of images will slide over and the new middle one will animate open to show the full image.

Screen shot of basic idea: Loading the XML and images and such is no problem...adding them to the stage and setting a mask for each, no problem.It's the actual functionality of getting the whole group to slide at once and the next image mask in line to animate into the center position while the current center position mask animates back down to normal.
