www.imageshack.us is a very simple, fast, reliable free image host. It is perfect for linking to auctions, message boards, journals, and other websites. Imageshack lives on a fully redundant, load balanced web cluster that should guarantee maximum uptime and performance. There is no registration or login, all you have to do is submit your picture.
For our members convenience I have enbedded the imageshack upload software into our forum. Go to the bottom of our mainpage and use the upload form !
Don't be fooled by the name TinyPic. This does not mean your picture will be tiny, it means the direct link for the picture will be tiny (http://tinypic.com/1). The url is also guaranteed to be unique, so go try it!
