Note that you can't attach images to the bugtracker's tickets, but you'd rather have to post a link to some publicly available site.

These results can be replicated, however, when put through more functions from gd library, bug dissapears. Would append the image, however, since it is not mine I'm not sure. Test script: --------------- $image = imagecreatefrompng($_FILES["original_image"]["tmp_name"]); imagepng($image, $filepath); ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=73636&edit=1
