Adding image with low opacity over existing image

Well, I guess you can guess what this is for.

Is there any way (in XF/Zend or general PHP) to add a 30% opacity image, let's say, over another image like a signature or avatar? I think this sort of image manipulation is possible in Imagick, not sure about GD and I have no idea on how to go about it either way.

You know what makes it harder, the fact that XF has 3 different avatars in sizes in 3 different locations independently... I'd rather prefer an avatar.php solution.
