I'm working with the Tiga theme, and while everything else has come together pretty well, the header is giving me headaches. I want to put a full-size image in the white space where the header is located, or maybe even Google Ads, but it gets all weird in different resolutions. To use up much of the space at 1160x842 (or slightly smaller), the image/ad has to be about 750px wide.
Obviously, this causes problems at 800x600, which is obviously still widely used, including by my client. If there are any tricks to fixing that, or getting the page to read what resolution is being used (use Ad "A" at this resolution, use Ad "B" at the smaller), I'd love to know.
