Detaching multiple clipping mask shapes/images after using compound path

Hi,

I am trying to take a single photo and break it into individual, multiple shapes/images using the compound path and clipping mask commands. 

In the example below, I have made the shapes (squares) that I want to apply a clipping mask to:

Next, I made those four squares into a compound path, so that I can have multiple clipping masks, and apply the clipping mask:

Then, I tried releasing the compound path so that (I thought) I could move the four squares individually:

But, when I do, the images disappear.

Please advise. I have looked for solutions in this discussion forum, and online. 

Thanks,

Abigail
