How to add an image to an e-mail?

Seeking examples of online services (file hosting, fax, email, image hosting), what else could I add?

• I considered building a website which offers subscription based file hosting, but I've also contemplated adding additional services for the purpose of diversifying and to be somewhat more outstanding by making a variety of services available within a single location. In addition to file hosting, fax transmission, and perhaps image hosting, what are other practical and viable services I could offer?

• Answer:

  They could set up a schedule, and you call or email to remind them when the date or time is nearing. Also, you could have them do something like order movie tickets for them, like an online planning service. I can't think of what the name of that service is, sorry, I tried. Hope it works out for you though.
