FleXMLe Gallery v1.0
Small (49.7Kb published with an embedded font), flexible (a lot of things can be tweaked from the xml including position, rotation, animation settings, timings, easing functions for each graphic file/swf that you show through the gallery), resizable (custom fluid layout).
Description for each item supports unicode (special characters) and hyperlinks, CSS stylesheets, font embeding.
Has also autoplay with configurable delay, scrollwheel(with mac support), keyboard navigation. Also supports “infinte” categories of items.
Since you have access to the actual position of the items and rotation you can also create categories (sets) of items in a geometrically organized manner and you are NOT constrained to have pictures with same dimensions or grids like in other products, that would make the set seem overly organized.
This sort of flexibility gives you endless possibilities in organizing the sets!
