YEs, but images 2,336 x 3,504 = 8,185,344 pixels @ 24bit color roughly equals to 24MB. That is lots of images even if you are on native resolution retina display. And doubling that gives you 48MB only. ( And someone has pointed out they are compressed differently within memory, so likely only consuming 1/2 to 1/3 memory size )

That leaves with 200MB memory gods knows what they are.
