Best way to deal with this banner issue.
 

My header code below.....

The page looks great, but when someone runs a res 800X600, the banner appears to be off the screen to the right, making the rest of the page look off.

I run 1024X768 and it looks perfect to me.

I figure the easy way out would be to somehow center the banner so that it os off to the left equal to the right, but that doesn't seem to work either.

What is the best way to deal with this? Have different size banners? somehow resize?

Is there an easier way?

I am thinking it looks screwed up in other resolutions as well, but didn't check yet.
