Overlapping Images with GD

Often, tutorials covering the GD libraries and it`s available functions in PHP will show how to overlay text onto images, manipulate images (resize, flip, rotate, etc) or how to dynamicly generate charts or graphs from numerical data. I have not seen many demonstrating how to combine images (or moreso, placing a transparent forground image over a background image).
In this tutorial, I will demonstrate how to place an image over another image which may come in handy for many uses including, but not limited to: applying a signature or logo to a photo, adding a "watermark", placing an object onto a background or whatever else you might image useful.
