Fatal Error - Attempting to upload Images

I am attempting to upload images to the website, which is proving to be temperamental.

At first, an error message appeared stating “An Internal Error Has Occurred”. Asked the developer to enable debug mode (http://discourse.cakephp.org/t/error-an-internal-error-has-occurred/577) and this shows now Fatal Error (see attached image)

Can the image be reviewed to identify what the problem may be?

Kind Regards,

PHP doesn’t have a built in function called imagecreatefrombmp(). Maybe imagecreatefromwbmp() was what was intended.

Also make sure you have the gd2 extension installed.
