Since CGImage is derived from CFType you can just do:

The reason being that CFType knows how to handle a -release message,

Be carefull when you mix CFType memory management, and obj-c memory

It works well when you do not use GC, but may become problematic if
you do not take special care with GC code.
If I'm not wrong, it should be something like this:
