Inserting images as BLOBs - any way to avoid using base64encode?

Hi Viktoras - the problem with storing images in a stack is that you have to
read the entire stack into memory even if you only access one image (whether
it's in a custom property or not). I've your suggested approach before but
with each image having its own stack to get around the memory issue - I
don't want to go down that path this time though.
