Is it possible to export each layer as its own file without having to manually select each layer and go through the usual steps to save, preferably just using the layer name as file name?

Is there any way to make them a specific color or change their size? I didn't see anything in the settings.

did you ever figure out a way to do this for your thousands of images? You might try Mathematica's ImageAlign feature, they have a 2 week trial. Hobbyist license isn't terribly expensive, wish their biz license had a tier for small biz that have yet to even profit For your example (assuming all your pictures are cars) I'd create a new image by erasing everything but the wheels on the car, then align each of the thousands to that template. Their function finds the corresponding points automatically.
