Well, that gets us partway there. Looking at the docs, it looks like

Also: right now (unless I've missed an API somewhere) to validate
images you must pass them to the Image

image,
I still have the issue with the output side of the image.
(I realize that, when validating, you can always resize the image so
that it's likely to be less than 1MB when finished. I just wish there
