Image recognition

I need a script that can read text of an image. The images are very simple (not captcha): Same font, same background and the text is located at the same spot on every picture. Imagine a site with a photogallery (php), there should be a button by every photo. Once a user clicks the button, the script reads the text of the current picture and loads a new page displaying that text. The gallery is ready, I need you to make that magic button for me! Edit: I have changed the sample picture, hopefully this one will make you understand this project better. At the top left corner you will see "File name: american_dad...". I need this script to be able to read that, and transformer it into text.
