This way you could use a function more like the one you showed which checked the extension. For example switch($_FILES['imagefile']['type']){ case 'image/jpeg': $im = @imagecreatefromjpeg($file); break; case 'image/gif': //etc. etc. If the image files you are trying to open had been uploaded by a user, the file type would be in $_FILES[’imagefile’][’type’] where imagefile is the name of the form element which uploaded the image. This way you could use a function more like the one you showed which checked the extension. For example
switch($_FILES[’imagefile’][’type’]){
case ‘image/jpeg’:
$im = @imagecreatefromjpeg($file);
break;
case ‘image/gif’:
