note 28298 added to function.imagetypes

Please note that if only "GIF Read Support" is enabled, the IMG_GIF bit will not be returned (at least on my system: PHP 4.3.0/RH Linux 7.2). To work around this issue, and also the issue that there is no function that can tell me what image format a GD resource ID refers to, I use the following switch statement to map the exif IMAGETYPE_* constants to the GD IMG_* constants: switch (exif_imagetype($file['tmp_name'])) { case IMAGETYPE_GIF: $image_type = IMG_GIF; break; case IMAGETYPE_JPEG: $image_type = IMG_JPG; break; case IMAGETYPE_PNG: $image_type = IMG_PNG; break; case IMAGETYPE_WBMP: $image_type = IMG_WBMP; break; default: $image_type = 0; break; } store this value together with the image data in a database and later use the following IF statement to see if I can work with that image (create a thumbnail, etc...) if ($image_type & (imagetypes() | IMG_GIF)) { return $this->createJpegThumbailFromString($data, 46, 27); } else { return file_get_contents($_SERVER['DOCUMENT_ROOT'] . '/gfx/no-thumbnail.jpg'); } HTH anybody...
