I've been looking for a customisable flash image viewing app for a while now. I know there's a few out there but this one i just like the style. SimpleViewer has a small footprint of 12kb for the actual .swf file, then depending on the amount of images a small .xml file which hold all the settings. Along with the set-up guide for the XML files, you can also downloads .cfm, .asp, and .php files which help you build the .xml via forms.
