The generator is almost done, I'm just fine-tuning it.
EDIT: Well, it's done. I couldn't get opacity to work, either on text or background, so it's just solid color on solid background.
It doesn't round square corners like an image-editor does, so it looks slightly less pretty in that aspect.
It was nice practice though since this was my first time using PHP's image functions
