Complicated PHP image generator: How was this done?

http://www.mweor.com/createcustom.php You need an account to see it. They're free: http://www.mweor.com/index.php Feel free to use fake information but I think there's an activation email. (I don't know I'm actually using a friend's account to go on there, lol)

Anyway, how did they do that? I want to do something kind of similar. I want to make a dog coat color generator where to put it in the simpliest of terms, you tell it what coat color, what kind of markings, etc. and it generates the picture.

I did not look at the site, as I really don't feel like taking the time to register. If, in fact, they did it via PHP, they either used the the [man]image[/man] functions or the [man]imagick[/man] functions. However, I would think the sort of thing you describe might better be done via Flash, or possibly the new HTML5 "canvas" element, allowing the browser to handle more of the functionality.
