Increase width of my style. Ads cause problems
 

I am trying to implement a left skyscrapper on one of my fixxed skins.. However this completely breaks the layout on the Forum display pages.

Here are some screenshots. You can see that the header's size is too small and needs to be adjusted. However the central content table should also be adjusted, hence the advertisement itself is 160 px in width. So it should be 200 px or something. The last screenshot shows you a style where it is automatically adjusted, however the content table still seems to be too small.

Visit my website, change to Element Skin, then have a look here:
http://www.d3scene.com/forum/, here: http://www.d3scene.com/forum/world-warcraft/ and here: http://www.d3scene.com

You will see that the first link greatly breaks the layout. The second link only breaks the layout on top a bit (like 2-3 px, if you look on the top right corner). The third link shows again that the the header size is too small.

I used this guide to implement the advertisements:

Thanks a lot

It appears the table for the header image & bg image is hard coded for width size, increase it.

yep. Thats where my problems start. Where should I have a look?

oops, thought i put "header template" in there.
