i installed the latest version of the plugin and went to experiment with it, yet found that soon after i created some test galleries, my media were somehow appropriated by the flash album gallery, and did no longer show on the website's pages, though the file names still existed in my media library. after disabling and removing the plugin the actual files had also disappeared - i doublechecked this on my server.
in my opinion, a plugin like this should not touch the media already present on a website, and if it uses whatever may be referred to from a page, not move, nor in any way alter, already present content, which was my experience here.
too bad! it looked like a promising plugin, but in my experience unsuited for websites that already run content, and i have seen no warning concerning this serious malfunction.
