Sounds like your email provider has a size cap on the emails you can send. You'll need to check with them to see what your options are or, as was indicated, send it via a different email.
When I receive an email with many photos etc, there is no problem. But, if I try to forward that email to friends, it appears it is too big as I get a message saying "Try later" or "Use another server". Must be some adjustment I can make on my Mac???
I have a a Mac Mini, OSAX 10.6.7, 2.53 GHz, 4GB
Mail version 4.5
