A few issues as a graphic/website designer that I can immediatly
think of is this..
1) Would need some serious bandwidth, not talking 20k images here
either. Each image could be 2-3 megs. With that many people
downloading and uploading the costs would be enormous. So, having
said that would need some financial backing. Memberships,
advertisements something that would generate money for the server
and bandwidth cost.
2) Would need each image to be approved my admins before it was
uploaded. Surely there might be images that should clearly not be
worked on. Humourous or from a legal standpoint. So that means a
hand full of people working around the clock to ensure the standard
and quality a site like this needs to be maintained properly.
3) I personally think that if I was to upload an image to a server
to have people to work on it then I would hope the "worker" has a
colour calibrated monitor. Paying good money for someone to
"correct" your image(s) only to find out when you printed it or had
them printed, and they turned out poorly. What looks orange on one
monitor could infact be brown. Contrast and colours would need to
be bang on.
Yeah, it's a good idea, but it needs more thought.
Oh, and if anyone wants to go ahead with it.

I'll design it!!
i would suggest something like a Wiki where we could build a base of community knowledge. Or a Blog would allow more authorship information, but be less subject oriented... i could probably help with a blog, as i have access to the Harvard blog.
