Different colour/image in profile postbit.

[killerford]

I'm wanting to know how I can change the colouring or having a image background where the postbit profile is, as it's just normal plain to match the forum I wanted to change it so it's different and stands out more.

Can anymore help me please?

Can you provide a screenshot?

I'm wanting to either change the colour like this

Or what an 50% image behind it like this

I was woundering if it's possible to have different groups with different colours and images?
