It’s a simple XML gallery with support for categories. Simply add the category attribute to the XML entry. Here is an example of a typical xml node in the file;The categories don’t need to be in any order, you just add nodes that look like the one above and put them in any order you want. The swf will root out all the categories from the XML and get a pic from each category to use as it’s thumbnail.
You can add as many categories and as many pics as you like. You can also resize it or set it to fullscreen mode (the gallery can adjust to use the extra space).
