Replacement image.

An image wishing to replace itself with another image (in a style similar to a Unix exec() call) should return from its exec() method with the replacement image set to point to the new image.

If an image unregisters itself as a result of being executed, it must make sure that its replacement image (if any) is registered, otherwise the replacement is likely to be freed before it can be executed.
