Hmm how about -->
http://imgair.net ?
P.s I run it
its been running for the last 1.5 years, host about ~20k images, 4 servers behind it, should work
The problem is existing posted images and future user content, since you can't really tell everyone never to use imageshack again. Unless you run an imageshack proxy?
Hmm true moving old posted images would take a while to do unless there's someone can code up something, i'll be more than happy to work with them to get the images ported over to imgair..
Nah, I don't run an imageshack proxy, the images are stored on our server's (in USA, UK and Italy)
