X-Cart forums - Top Banner Store Front

Hello, I have a little problem and I know its probably pretty simple to solve but I just cannot fix the issue. As you can see in the picture, I have my logo on the top rleft but I would like to either extend the lenght of the picture to the other end(right) or insert a picture on the white space to the right of the logo. Unfortunately I dont know whats the file(if any) to add a picture on the white space. So, I tried extending the lenght and when I do that, the home, shopping cart and contact us link mover all right and disalign. Can anybody help me out. I tried webmaster but cannot solve the problem.
