My iPhone broke and I want my pictures off of it

My iPhone 4 broke, I'm not sure why but it won't turn on anymore or anything. I want my pictures off of it! I used backed it up on iCloud frequently but I have no idea how to retrieve the pictures from it. Please please please help!

Try holding the lock button and home button at the same time. If that doesn't work, plug the phone into your computer and restore it.
