How can I add a background image to a plugin?

By yoram

I am trying to build a small social network for little kids and it need's to be very colorful.

For example, I want to put a background image to the "blog" plugin - like in the exaple I put here.

I did a few testings but didn't come up with somthing.

I will appreciate your help.

Thanks... Yoram
