Image + TCP Connection

Hey, I've made an email sender and I was trying to include an
image to the email but I'm not sure how... does anyone know?

I don't know how, but I'd try to find some information about the mail protocol. I assume you are using SMTP. This Wiki page seem to be a god point to start, gives various links to RFCs:
http://en.wikipedia.org/wiki/Simple_Mail_Transfer_Protocol

Ok, thanks that helps!
