Does anybody know how this can be done?

[B_Pages]

Hello,
Below you?ll see two images containing my current setup which is repeated throughout the forum, and the one I?m trying to get. I?ve seen this on several other forums and I was wondering how it can be done.

The two category bars need to be switched around (blue on top, red on bottom) and an image needs to be added to the right side of the blue bar only.

Any help would be greatly appreciated.

Thanks to all in advance!
