If you just point the cell to a TImage it doesnt create a copy of the image, just changes the pointer to were the image is.
If the image isnt refferenced anywhere else, then just pointing the array cell to the new image makes the GC destroy the old one.
If you point a cell to NULL, then the above happens, but the array is the same size. (ie the same number of pointers)
