Yes, but only as a background, the title will still be displayed as ClassicGameRoom on top of it. I chose the yellow background to give it that old pub feeling we had in the Wind Squid forums. It was a hard find, but it was worth it because is very close to what it was.
The white space is part of the banner so I couldn't change that. The site kept putting it on the left, I was only able to center it after I found the settings were doing that. Otherwise it was all the way on the bottom left. I'm glad you guys like it.
