All you need is a phone case with a clear back (for iPhone 4/4s like mine, the cheapest ones I have found are HERE), a craft knife and a photo / printed picture / a picture from a magazine.
You can use a template to make sure that your picture will be the right size, like this one for iPhone 4 / 4s. If your phone is a different model you should be able to find a template on Google. Then trace the hole for the camera on to your picture and cut out using a craft knife.

Just place your picture behind your phone into the case and you will have a unique phone case that you can change as often as you like without having to buy a new one!
