Re: #2 there. You are much better off simply rejecting the email at SMTP
time with a simple, short message. Short because some email clients and
servers out there are stupid and don't return error messages.
If you generate an email for every single message that comes in lacking
an image you are going to become a source of spam for every single
spammer that decided to add your email address to the their mailing
list. It might not be their spam that is sent out, but you will be
sending your spam to randomly generated from addresses until something
melts.
