Following files: bg.png - Clear Transparent Image 14416fed5d4f78.jpg - Normal Jpeg Image The Code: header('content-type: image/png'); $watermark = imagecreatefromjpeg('14416fed5d4f78.jpg'); $watermark_width = imagesx($watermark); $watermark_height = imagesy($watermark); $image = imagecreatetruecolor($watermark_width, $watermark_height); $image = imagecreatefrompng('bg.png'); $size = getimagesize('bg.png'); $dest_x = $size[0] - $watermark_width - 5; $dest_y = $size[1] - $watermark_height - 5; imagecopymerge($image, $watermark, $dest_x, $dest_y, 0, 0, $watermark_width, $watermark_height, 100); imagepng($image); imagedestroy($image); imagedestroy($watermark); The Problem: The code above works fine in sense of syntax! bg.png acts as a transparent border for 14416fed5d4f78.jpg to keep the size of bg.png and not the size of 14416fed5d4f78.jpg so it doesn't blow up 14416fed5d4f78.jpg. However, the image comes out black/white and has lost its color! I looked all over Google and I've found nothing so far that's functional to give the new created png file the correct colors as the original 14416fed5d4f78.jpg. I figure that I'm missing some small elements to the process of creating the pngŠ Anyone have any ideas, pointers, advice, or correct solution to make this possible?

Travis: Try this: $original=imagecreatefromjpeg("mydog.jpg"); $watermark=imagecreatefrompng("copyright.png"); $osx=imagesx($original); $osy=imagesy($original); $wsx=imagesx($watermark); $wsy=imagesy($watermark); imagecopy($original, $watermark, ($osx-$wsx)/2, ($osy-$wsy)/2, 0, 0, $wsx, $wsy); //center imagepng($original, "trans.png"); The code works here: http://webbytedd.com/b/watermark/ Cheers, tedd -- ------- http://sperling.com http://ancientstones.com http://earthstones.com
