Drag in several layers thinking about where you want to place them. Once they are scaled down to be slightly larger than the 'cell' layers, go ahead and do some layer organization in the layers palette to bring each layer directly above the actual cell layer. Do this for each.

Go to Layer: Create clipping group or mask (depending your version of Photoshop) or Ctrl/Cmd G when on the layer you are going to clip (with the corresponding cell layer right beneath it).

Go ahead and place each image above the cel in both the design AND the layers palette (otherwise you might clip a layer, wonder where it went and have to drag it across the screen in the document to see it). It might happen to the best of us...

Spice things up by creating a gradient stroke under layer effects on one of the layers. Now drag this layer effect to the other cell layers (not the image layers) in the layers palette. If you want you can go in and change the angle of the gradient on some of the layers.

Ok, I decided to do a little different picture selection. You can see the gradient stroke effect on each cell layer (feel free to change the settings). It's nice to do minor things like this to just enhance the overall effectiveness...small details like this can just 'make' a design that much more professional and you've got lots of options at your disposal. In this case though you want it to be a subtle complement or afterthought.  You can have this .psd in your Photoshop to better help you understand the design from the iPSDirectory

Here you can see how the clipped layers look. Remember that you can move the image layer around 'within' the cell with it selected in the layers palette but when you select the bottom layer (fill layer) you move the entire clipping mask/group around.
Ok, it's bugging me now but that tunnel scene needs to be in the middle not on the bottom. Also start thinking like that...think about balance and which images would look best where.

You can clip even large layers like this as long as they are above the appropriate layer in the layers palette (Ctrl G). Then you can nudge it right into place.

Here I've spent way too much time on the guidelines (for this tutorial) but you get the idea. On a real production you'd want everything perfect.

With the guidelines in place it becomes very easy to create new fill layers. Grab your rectangular marquee (M) starting at the intersection corner of guidelines and they will 'snap' into place. You have previously laid out the guidelines where you want this next fill layer for a text backdrop to be.

Remember to be creating new layers to 'fill' these marquee 'selections' onto. Run another marquee across but make it very thin. Do this right above the large fill. Now drag this layer to the new layer icon to duplicate it and hold Ctrl click and drag it straight down to the same location beneath the large fill.

Here I've done it all the way across to show you some more editing. I'm making a selection as you can see but I'll have to switch to the appropriate layer in the layers palette and then Ctrl X to cut the extraneous portion out. Do this for each extension. Since the guidelines were already there, you could just start from the first left vertical guideline.
