Okay...so i'm making a div overlay for myspace...here's the image.. The yellow box will end up having text in it. So.. any suggestions on what I can add to the image to um.. decorate it because it's very plain right now. Or, what are any suggestions on how I could improve it?

put some nice pictures on it like shapes and stuff things you like

peace signs, rainbows, rock and roll hand gestures or a beach ball or something haha

Tone down the bright colours and try to save things in the PNG format, Now you have saved it as JPEG you won't be able to recover the quality loss
