Photoshop Creative

I was given a nice set of masks.
I brought up a picture and then a mask as a new layer(the masks are jpg.)
I have been experimenting and trying...... but how do I get the mask to show the picture through the center of the mask?

I think I can actually answer this one by giving you these directions and a link from whence they came.

1. Open your mask and the photo you’d like to grunge-i-fy in Photoshop.
2. Duplicate the photo onto a separate layer (right-click on the photo background layer and choose Duplicate Layer). It’s always better to work in a copy of the photo.
3. Turn off the original photo layer.
4. Drag the mask onto the photo.
5. Resize the mask to fit the photo (Edit>Transform>Resize).
6. In the Layers palette, drag the mask layer BELOW the photo layer.
7. Select the photo layer in the layers palette.
8. Hit Ctrl-G (Ctrl-Alt-G in PSCS2) to create the mask.
You should see the edges of your photo masked out by the layer below them.

If you like your photo to bleed into the edges of the background, simply link the layers together and drag them onto your layout.
If you’d like to add a black (or any other color) border:

1. Create a new layer and position it at the bottom of the stack in the Layers Palette.
2. Use the paintbucket tool to fill the blank layer with the color of your choice.

two things to try are these two different blend modes screen and multiply. If one does work the other will. It all depends on the color of the mask.
