Is there a mod that automatically places [img] bbcode on a pasted image links?

So for example, when you paste a link to an image like http://i.imgur.com/mH0N8.jpg, it automatically adds the [IMG] flags.

I've seen this implemented at Something Awful and I would love to get it for my forum.

Nice idea but i doubt if it exist - no idea sorry - havent seen anything around
