When you are transmitting a binary file, like a picture, the actual size of the transmission increases.
Why? Because the binary data is being transmitted in visible characters, sort of 6 bit "bytes". In other words 8 bit bytes are expanded into 6 bit "bytes". So the size increases by at least 8/6 = 33%.
On top of that you have all the mail headers.
View the "Message Source" of a received message containing pictures sometime and note the
"Content-Transfer-Encoding: base64" tag preceeding the block of 6-bit ASCII characters representing the picture. 6 bits gives you 64 possible characters.

Marv;
How does your e-mail system add-up bytes? I sent a posting that had 3
attached files totaling 82KB. The letter itself was 224 bytes. It was
rejected as beign over 100KB.
Maybe it's time to increase the limit?
