Photo submission form question

I've been asked to set up a photo submission form that will collect obituary photos with obituary notices and be emailed to one of my co-workers. I've never done this, and while I think I know the mechanics, I would like to ask here exactly what is involved in creating a photo submission form and what I should know. I already know very well how to set up a regular message submission form with validation and protection against hacking/spamming. I just feel that a photo submission form is somewhat different. Am i wrong?

Also, examples that I can modify for our use would be nice.

Thank you for your help!
