imagecreatefromjpeg crash

Greetings, I am having a very peculiar problem trying to use imagecreatefromjpeg (indeed, ANY of the imagecreatefrom... functions) under both Windows and FreeBSD. First off, here are my server specs: Win: apache 1.3.23, php 4.2.1, GD 2.0 or better BSD: apache 1.3.26, php 4.2.3, GD 2.0 or better And now the problem: I am trying to use imagecreatefromjpg() to load in an image so that I can copy parts of it to other images. Here;s the code: $orig = imagecreatefromjpeg('46880_img.jpg'); // initialize the image parts for the email form $cell1 = imagecreate (468, 29); $cell2 = imagecreate (231, 25); $cell5 = imagecreate (468, 26); //copy the parts of the original banner to the individual cell images imagecopy($cell1, $orig, 0,0,0,0,468, 29); imagecopy($cell2, $orig, 0,0,0,29,231, 25); imagecopy($cell5, $orig, 0,0,0,54,486, 26); $c1 = imagejpeg ( $cell1, "cell1_img.jpg",80); $c2 = imagejpeg ( $cell2, "cell2_img.jpg",80); $c5 = imagejpeg ( $cell5, "cell5_img.jpg",80); $c7 = imagejpeg ( $orig, "orig_img.jpg",80); On windows, I get: "php.exe has generated errors and will be closed by windows". The apache error log shows: "Premature end of script headers: f:/nusphere/apache/php/php.exe" On BSD, I get: DNS error in IE Netscape just waits forever. If I comment out the imagecreatefromjpeg function, the script behaves as expected on both systems: The imagecopy functions complain that the original image doesn't exist. Note: I have tried to fopen the image, and use imagecreatefromstring with the exact same results. Is this a problem with GD? Is there a workaround? Thanks, Keith
