Image Space is the virtual address space in use by the images being executed by the process.  This is the sum of all the address space with this protection allocated by images run by the selected process  Write Copy protection is used when memory is shared for reading but not for writing.  When processes are reading this memory, they can share the same memory, however, when a sharing process wants to have read/write access to this shared memory, a copy of that memory is made for writing to.
