GIF instead of JPG..

Hi, I found this beautiful piece of code on the php site which make a proportional thumbnail, problem is its only working with JPEG files...and not with GIFs, can someone please help me convert it to GIF too? I tried but got a bit confused as there are no functions that are equal to "imagecreatetruecolor" that is in the below script. The below script works perfectly for jpgs: <?php // The file $filename = 'test.jpg'; // Set a maximum height and width $width = 200; $height = 200; // Content type header('Content-type: image/jpeg'); // Get new dimensions list($width_orig, $height_orig) = getimagesize($filename); if ($width && ($width_orig < $height_orig)) { $width = ($height / $height_orig) * $width_orig; } else { $height = ($width / $width_orig) * $height_orig; } // Resample $image_p = imagecreatetruecolor($width, $height); $image = imagecreatefromjpeg($filename); imagecopyresampled($image_p, $image, 0, 0, 0, 0, $width, $height, $width_orig, $height_orig); // Output imagejpeg($image_p, null, 100); ?> Beautiful, isnt it? Hats off to whoever wrote it and three cheers for the online manual! Thanks, Ryan -- No virus found in this outgoing message. Checked by AVG Anti-Virus.
