I would like to second the suggestion of checking for desired width
before starting the stitching, rather than allowing users to spend hours
trying to stitch an image which is too big for the jpeg library, only to
have it error near the end.

Even better would be a helpful message saying "this image is too large
to stitch as a jpeg, try writing it as a tiff or png instead".
