Outsource picture hosting

Is there a way for me to outsource the pictures in phpAlbum?

My VPS is rather weak and slow, and hosting pictures for more then a couple of people is doable but goes slow, therefore I am considering outsourcing the service to a free hosting service, is there a way for me to to so?

If so, how, technically it should not be that hard, but my skills in the PHP language are VERY limited.

Love the software though
