How do you hang clear picture frames with clips (like those from Ikea)?

The frame is really just a piece of glass that sits on top of the picture and there is a cardboard with punched out rectangular holes which goes behind the picture. Ikea also gave 4 metal clips that go with each frame. I've no idea how to hang this on the wall. Do I have to use nails? I wanted to hang 16 4x6in frames in a rectangular shape... Is there a way to hang these up without making a bunch of holes in the wall?How do you hang clear picture frames with clips (like those from Ikea)?

I've got the perspex version. Easy way is to get a length of cord and tie it to the side clips on the back of the frame. There should be enough cord so that when you pull it tight it's about 2-3cms (1 inch) below the top of the frame. A single nail, screw or picture hook will hold the frame up.
If the clips are the kind used to hang mirrors, you hold the frame in place and secure the clip with your other hand and have a friend screw the clip into the wall. It will make a bunch of holes if you're going to do it 16 times... why not invest in a collage frame? That only takes one hole to hang and is a lot easier.
