XML Flash Gallery (And flickr)
XML Flash galleries are very easy to use & update. When there is a flickr support too, than it is great as it will be totally automated.
Polaroid Gallery is a free flash gallery with splash effect that can get the image data from an XML file or a flickr account.
Pictures is automatically scaled, centered and smoothed when they are loaded. Splash loading effect is totally random, this makes the look of the gallery different every time it is loaded. Images can be dragged & dropped anywhere in the gallery.
Besides the image gallery SWF file, FLA source can be downloaded too.
