Yes, I tried one hosted on PB, which failed again. The Imgur pic was a one click insertion. If you go to the "USE FULL EDITOR", and select Post Options "HTML and UBBCODE", then all you have to do is add the Imgur BBCODE hyperlink into the post anywhere you want it.
Also, Imgur provides a resize option for loading pics, and that can eliminate 2Meg+ pics. I like the *800X600 option. It seems to fit most current monitors.
