I was looking to detect the format of images, Im not sure if this is the best way but it works for me.

<?php
$filename
= 'http://static.php.net/www.php.net/images/php.gif';
$size = getimagesize($filename);

switch (
$size['mime']) {
    case
"image/gif":
        echo
"Image is a gif";
        break;
    case
"image/jpeg":
        echo
"Image is a jpeg";
        break;
    case
"image/png":
        echo
"Image is a png";
        break;
    case
"image/bmp":
        echo
"Image is a bmp";
        break;
}
?>
