I need to process these images using the GD librar

Answer 1

you can use this function too. it not require any other dependency. and work perfectly for other types also.

function _getmime($file){
    if($info = @getimagesize($file)) {
        return image_type_to_mime_type($info[2]);
    } else {
        return mime_content_type($file);
    }
}
