Unfortunately, I have hand coded it myself in PHP. Couldn't quite get what I wanted from those other products. They were all too big and bloated.
The site is mainly for artists to submit their work. It's incredibly easy to use (as artists aren't always the most computer savvy). It will determine if the picture is landscape or portrait, create the appropriate thumbnail and index the whole lot.
As I said, it's very simple but easy to use.
Now if there were a user accessible iPhoto plug in for PHP that would be really interesting!
Might have to try something with AppleScript....
Ta for the responses....
