Image Space is the virtual address space in use by the selected image with this protection.  Execute Write Copy is memory that can be executed by programs as well as read and written.  This type of protection is used when memory needs to be shared between processes.  If the sharing processes only read the memory, then they will all use the same memory.  If a sharing process desires write access, then a copy of this memory will be made for that process.
