I want to create one of those images with a word in it using PHP and ImageMagick. I have already gotten a word in the box with a patterned background however, i dont think its very good. Does anyone know the best way to do this? How could I rotate the individual characters? How can I make the background pattern random?

Those thingelings are called captchas. Maybe you find a good tutorial.
Also take a look at http://en.wikipedia.org/wiki/Captcha , esp the sections Circumvention and Defeating CAPTCHAs
