Before doing that, please consider not using JPEG for the images. This
sort of image is blurred by JPEG encoding and normally compresses
poorly. Once compressed with JPEG, it is not possible to get good
compression by recompressing with appropriate algorithms.
PNG is probably the best commonly available algorithm for this sort of data.
JPEG is for continuous tone images with predominantly low spatial
frequencies (people and many natural scenes). This image is discrete
tone with most information in high spatial frequencies.

Emails are not formal business letters, whatever businesses may want.
RFC1855 says there should be an address here, but, in a world of spam,
that is no longer good advice, as archive address hiding may not work.
