Image and hyperlink

I've seen a lot of users that have an image of there game with a hyperlink to it on the bottom of their forum replies.   How do you set that up? It seems I have to either pick an image to insert or a hyperlink with text. Plus it is at the bottom of their replies automatically(I think).

You edit your signature in your profile, and use BBcode. Keep in mind the max height allowed for forum images is 120 pixels.

Not sure what BBcode is. Could you give me an example text so I can match and insert my info?

Check this url for an example (RAW paste data is what you want to copy + paste)

Thanks Tom!
