</example>
This example uses <function>imagecopymerge</function> to merge the stamp
with our original image. Using this we can set the opacity of our stamp -
in our example we've set it to 50% opacity (another term for transparency).
In practice this would be useful in copyright protection as semi-transparent
watermarks are hard to remove yet allow viewers to see the image.
