[PHP] Manipulate an image with GD

Hello everybody!

I need some help with PHP!
My question is:
I’ve got this image: http://extreme-redeemer.com/math_captcha/image.php
As you see, it’s a math problem.
The numbers used are between 1 and 50, and the three operators used are: + - *

I actually want to decrypt this image so I get the 3 different parts ( number 1, operator, number 2 ) in text, so I can actually to this operation.

I know PHP well, but I’m not familiar with the GD library!

Thank you so much!
