Well what do ya know. When I open my e-mail this morning I also received a reply from Imageshack acknowledging a problem. So I guess it wasn't a figment of our imagination.
I realize that not everyone has experienced this issue and I never felt this was a forum member problem but rather a problem with ImageShack that has been persistent, reported and documented for several years now. Imageshack has also been hacked on several occasions and has acknowledge problems with its image hosting service and security.
Just a suggestion, but users might want to consider switching to using another web based storage / posting sources for there pictures. There are others.
