This software seems to work well for other people, but I found the upload of photos to be confusing. It asks that you create a category before uploading, but there's no place to create the actual category. I sought help on their forums and they were very nice, but they seem to think the software is completely intuitive, which it is not.
One thing I can say is that it installs like a breeze! 2 clicks and boom, you're done. But with no end-user documentation, I can't see using it, because if I can't figure out how to use it (and I'm a web developer) how are my visitors supposed to? Especially when basic end-user documentation doesn't exist!
