Go to http://picasa.google.com/index.html and download the free program. We are going to fade the images and apply them together, all at the same time.

Here are the two images that I am going to use .  Note that one of them is larger than the other.  If you want the images to be a perfect fit, the images need to be the same size, which you can do by cropping off some of the larger image or resizing.  For this tutorial, though, I will leave the images just as they are so that you can see the difference.
