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.

Thanks

An attachment adds a mark-up of ~35-40% to the total size of the email;
therefore, attaching a 800KB pic to a 150KB message becomes a 1330 KB
(1.3MB) email.

When you send a picture the total size of the e-mail is increased by about
33%. This is due to the encoding needed to send the graphic. So while the
message size increases, if the recipient was to save the picture, it would
be saved as its original size.

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.

ALL e-mail gets sent as plain-text. HTML-formatted e-mails contain tags
to encode bolding, italics, etc., but they are still plain-text. All
attachments, binary or text, are text within the message. They get
encoded into MIME parts that encode the attachment into a text block
that gets reconstructed by the recipient using their e-mail client to
read the MIME part. Everything in the e-mail that gets sent and
received is just text. Encoding binary files into a text block will
increase the number of bytes for that text which represents the binary.
