Replacing the Vbulletin button?
 

How do I do this? I looked in header and was able to put my logo in, but how do I replace the logo with the custom button I have?

Not sure exactly what you mean. I'm guessing this has to do with templates so i'll move it to that forum for now :)

I think by what you said you may be looking to change the {titleimage} replacement for that style :)

Could you give us some more info or a screenshot please?

To replace the buttons on the top of your forum you will have to go to the "header" template.

Go to your Header Template and find..
<!-- toplinks -->

Under that is where your button code is. Just adjust the code to your style.
