Sounds like a great beginner's exercise.  Something very similar is the 
basis for my first CGI tutorial* -- converting that to PHP would be simple
yet educational.

One bit that hasn't been mentioned yet (perhaps because the more advanced
folks here take it for granted?) is the image map of thumbnails.  I touch
on creating that but I'm not generating it dynamically; that might be a
fun exercise, too.  If someone has a way to do it that wouldn't overwhelm
my beginner-level audience I'd be delighted to publish it and give you a
plug.
