i'm not 100% sure exactly how you want it to behave though.-mouser
Maybe a concrete example will help. Imagine having eight screenshots of my software. I want to upload a javascript file to tinjaw.dcmember.com/scripts that does what I want and I just insert a line of script into tinjaw.dcmembers.com/MySoftware.html. Then at the place I inserted the line of script I see a 400x300 images of my first screen shot, and below it are thumbnails of all eight screenshots. I can click on the thumbnails to change what is displayed in the 400x300, and if I click on the 400x300 I am brought to a page that has the eight thumbnails but when I click on one it displays the full size screenshot at its native resolution. If I took a screenshot at 1280 x 1024, it displays it at 1280x1024.
The more I think about it the more I'm realizing that it is really no different than a standard app to generate a thumbnail gallery other than instead of making a bunch of html pages, it creates a single javascript file and provides you the code to insert into another html page.
