Thanks for the tip, I tried it and the image disappeared altogether. I changed everything back and got back to square one. I could only find one reference to kubrickheader.jpg in the stylesheet. I did, however find reference to it in a document called header-img.php located in the images file. Changing that had no effect either, but I found this in the document, which means nothing to me. Any ideas?
// Blank out the blue thing
for ( $i = 0; $i < $h; $i++ ) {
$x1 = 19;
$x2 = 740;
imageline( $im, $x1, 18 + $i, $x2, 18 + $i, $white );
}
