This has to do with lossy file compression (such as jpg) and has  
nothing to do email. Lossy compression throws away pixels resulting  
in file degradation, the lower the number the worse the result.

If the images are too large you might want to try a service such as  
yousendit.com and if you need to send multiple images throw them all  
in a folder, zip/stuff and send.
