plugin form with image upload

Hi,

noob here with a noob question:
I’m building my first plugin, which will show a list of people.
I’ve got it all done, except I want to be able to stick a picture to each name, and I want the content editor to be able to upload the image, and change it when possible.

How do I go about doing that?
can/should my plugin use another plugin?
or (how) can I code the image handling myself into my plugin?

any help will be appreciated,

thanks,
Omer
