It may have worked once but not anymore. Thumbnails appear after first installing them vanish. And support is absolutely non-existant. I'd gladly pay for it if worked. The same applies for the videos version of this extension too.
This module works great. It serves it's purpose, it's exactly what I was looking for. If I get the chance I would like to contribute to this module to allow for scrolling if there are more pictures than can fit on one line.
