Why when I send an email with a Jpeg attached does it end up a lot larger
when it gets to the recipient. Probably like an 800 kb pic ends up at
approx 1300 kb when it arrives.

Is that the size of the pic before or after the receiver saves it on his
hard disk?

If "before" then the expansion is the result of the way binary files (like
pictures) are encoded in order to send them by email. The increase should go
away when the pic is saved to disk.

If "after" then I don't know the answer unless the pix are somehow being
saved in a different (non-jpg) format.
