[size=+1]I use Flickr to post Screenshots to forums. You can upload by email or via the Flickr App. They have an option to grab the code to share. If you are Jailbroken, they have an App called Quickshotter. As soon as you take a Screenshot, it is uploaded to Quickshotter, and the [IMG] code is copied to your Clipboard. Hope this helped. Sorry about the late response.[/color][/font][/size]
