Look at the layers window. To manipulate a layer, you must first hilite that layer by tagging it with your cursor. Now hilite Layer 1. At the top of the layer window is the opacity control. It should read 100%. Hit the arrow to the right and move the slider that appears. Watch the image as you do this. You should begin to see the image fade away into the background. Choose a percentage that allows you to see both the face and the background together. Now we will align the images. With Layer 1 still hilited, select EDIT>FREE TRANSFORM. A rectangle with circles in the corners and one in the center will appear. You can move the layer by hitting inside the rectangle and dragging it into place. You can rotate the layer by hitting outside the rectangle, and spinning it. Notice it spins about the circle in the middle of the rectangle. You can move the point of rotation with your cursor. The next one is important... You can scale the layer by hitting one of the corner circles and dragging it in or out. NOTE: It is important to hold the shift key when you do this, in order to keep the image proportionally correct. Using the EDIT>FREE TRANSFORM command, align the face with the background. I usually use the jawline and eyes as a guide. After you have the images aligned as best as possible, slide the layeropacity level back to 100%.
