Combining two images

I use a PHP script as a random image selector. I would like to add a
small 'footer' image to the bottom of each one at runtime. I change
the pool of images regularly so it is not something I want to do in
photoshop, rather, I would like to find a way to do this in PHP.

Is there a way to attach two images together in this way so that they
are rendered as a single image?

+--------------+
| Main Image |
+ -------------+
| Footer Image |
+--------------+

Thanks,
Alistair
