Check if shrunk version exists before making it
Currently makes the shrunk version every time even if it’s already there. This is a bit of a wast of cycles. Should probably have some checking of age as well as existence to regen is original is younger than shrunk version.

I’d like to mix wide and tall images in a row and have them match height and have the widths figured out appropriately. Needs a quite different approach to current one to do that.
