In reply to benshelock, consider this:

<?php 
$path='http://www.hpi.co.uk/images/test/';
$file='15635_0_0.9955380731532122_ORIG.jpg';
$size = getimagesize($path.$file);
echo $size['mime']; //returns image/x-ms-bmp
echo $size[2]; //returns 6
?>

It's probably best to always handle it using the numerical value rather than the interpreted mime type.
