Resize based on resolution

On my boards, the top links for usercp, store, memberlist, etc stretch the header on 800 x 600, but look fine on 1024 x 768 or any higher resolution. If I make all the images smaller, they look bad on the higher resolutions.

here is the site so you can see: http://www.adgbc.com/bbs/

I would like the height of the images to be 27 pixels if the user is on 800 x 600 resolution but 31 pixels if the user is on any higher resolution. Is there a way to do this?

I think this would have to be done by JavaScript or DHTML so i'll move it to the forum for these issues

as a rule of them its always good to dev for 800x600
