The Compare and Contrast XML Image Gallery lets the user compare two images at once. It has thumbnails which the user can drag and drop into two larger image areas that also have a one-line description area. The user can also click the larger images which makes them size up to a full browser size. You can have as many thumbnails/images as you want and as many category gallery pages as the width of your gallery can hold. AS3 only. Opens with Flash CS3 . Step by step instructions are included and code is commented. Also, two html files are included to demonstrate SWF embedding for both full browser and fixed size.
