While this might be questionable (and I haven't tried it), this place allows you to upload content without question. The only big problem might be that they will probably overlook DMCA requests - http://bayimg.com/
A better place could be - http://allyoucanupload.webshots.com/
or meltingice's gallery, you can just link to that image.
Or Ashundar ;). I think we've got plenty of places to upload our images to.
This thread/topic is really not needed. There are literally thousands of places to upload images these days.
Wish I had known a few good ones. Maybe your knowledge has reached a point that it didn't need this, but I thought I did and supposed others might need it, too.
