Demo 2
The following example blends two images together using layer masks.

1 Open both marble.jpg and king.jpg in Photoshop.

2 Copy king.jpg into marble.jpg as a new layer. (You can simply select entire King's image, copy and paste it onto the marble.jpg file. In a newer version of Photoshop, you may also want to rasterize the copied layer aferwards.) Rename the new layer to "king" (See the image left).

3 Use the Move tool to reposition the king layer so that the image is aligned with the top of the canvas.

4 Add a Layer Mask to the king layer by selecting the King's layer and clicking on the Add Layer Mask icon (rectangular icon with a circle in it) at the bottom of the layers palette. A new square icon should appear next to the image which is the layer mask.
By default the layer mask is white which means it will reveal everything in the image. If you make part of this mask black, it means that part is transparent. Likewise, gray part would become partially transparent.

5 Alt-click (click with Alt key down) on the layer mask icon to view the layer mask in the main window. Now you can directly draw and modify the layer mask to make various transparency while keeping intact the original image of the king.

6
Pick the gradient tool in the tool bar, make sure that your background color is white and forground color is black, and draw a gradient in the image window (which is showing the white layer mask now).

7 In the layer pallate, click on the king's image to switch back from layer mask and view the effects of the gradient layer mask.
If you want to revise the layer mask, you may just alt-click on the layer mask icon again and redraw gradient or any kind of pattern. Or you can draw on the layer mask without seeing it by just clicking on the layer mask icon (instead of alt-click) and drawing a pattern.

8 To disable/enable the layer mask, shift-click on the layer mask icon.
