Email is growing in size

[BigStan1]

I sent myself a photograph attached to an email.  It initially left my computer as a 15.2MB message but when it arrived back at my computer, the email had an indicated size of 20.3MB.  Where did the extra 5.1MB come from?

   Maybe the header and footer info. That's a lot of megapixels in that photo!

Lots of possibilities.  Are you counting the size the picture was on your computer, that has to be converted to a format that can be transmitted.  Such formats are larger.  Also even if you outgoing email was that size, they may have converted the format of the Binary data transferred.  If you are using a client, you may be able to check what encoding the original and the message coming back used for the picture.

I doubt that just headers, etc. would cause such an increase in size.

The photo that was attached was in a JPEG format.  The size I posted was the value shown on the Apple Mail app, the original image was about 200K less.  The 5MB was apparantly layered on by Verizon.

Yes it was large, my camera is a Canon 5D2 (20MB FPA).
