Hi there all !!!

I was a bit bored about my signature here so now I want to make a banner for my site (you know with the name of the site, cool background, diff. BJ-pics, ... in it) You know a bit like the cover-art thing !!!! I would like the banner into my signature here on the board but don't have any clue how to do it and I don't think I have a good program for that as well

Anyone can help???
