Program: Photoshop CS3 but will work with older versions.
Phoebe (.hotADDICTION) wanted a tutorial on this one:

I'm going to give you a description the way I did it. Of course you change it how you want. Remember that this is only a walktrough. Nothing to rip. Just do it your own way.
1. Create a new image in the size 800x600 px (file>new). Of course you can make this any size you want. Doesn't matter, this is not the final size.
2. Take some pictures and desaturate them all (ctrl+shift+u). The graphic will look so much better with black and white pictures than colored. Blend them all together on the background. Be a little bit crazy and creative. Take a look at mine so far
CLICK.
3. Marge everything together and then duplicate the layer with the blend on. Put it on the layer mode Soft light and sharpen it until it looks good (filter>sharpen>sharpen). I over sharped mine a bit because I thought it looked more intense,
CLICK.
4. Add
THIS texture and put it on the layer mode Lighter color. If you haven't got that mode on your Photoshop, you can chose Lighten. It basically gives you the same effect. Erase the texture a little on those placed that it's to much over the faces. Erase till it looks good. Take a look at mine
CLICK.
5. Time for another texture. Take
THIS texture and put it on the layer mode Lighten. You image should look something like this now,
CLICK.
6. Now it's time to create a new image again (file>new) with the size 800x600 px. You will soon notice that I created a too large new image but we will fix that later.
Fill the new image with the color #616b6b. Take your blend and resize it (image>image size). You can resize it to any size you want, I actually don't know what size I took. Paste the resized blend on your new image twice! then move them to a nice position.
7. Now I took
THIS stock and blended it in the blend. I put the layer mode of it to lighten.
8. Marge stock with the rest of the blend.
Now create a new layer and fill it with the same color as the background (#616b6b). Create a mask layer and then start to be creative. Paint so you have a nice look of your blend. After I thought it looked good enough I marged everything and then sharpened it even more. Just to make it intense. This is how mine ended up,
CLICK.
9. Texture time! Take
THIS texture and put it on the layer mode Overlay.
10. More textures are on the way. Take
THIS texture and put it on the layer mode Lighten. Erase those parts who look weird.
11. Two more textures to go. Take
THIS texture and put it on the layer mode Hard light with an opacity of 54%.
12. Last but not least. Take
THIS texture and put it on the layer mode Overlay. As you may see now it's not as big as the image we've got. Place it over the pictures and then marquee the "textured area". Press ctrl+shift+e and then make a new image. Just click okay, the size should be as big as your selection. Paste it on the new image.
13. Now you just have to add some text and brushes and it's done.
