Anyone know how to override the WP 3.0 background function? I went to test out a 1 x 900 pixel image that is a gradient to tile horizontally only, but even though it works, I get a several errors showing in the admin when I upload the image. The idea is to limit the background image size for page load time. Basically I get Warning: imagecreatetruecolor() [function.imagecreatetruecolor]: Invalid image dimensions
Thanks in advance.
