Still not exactly sure specifically what you want to do, but I'm going to assume you want to sync photos to an iPhone with a Mac.
Plug your iPhone in. In iTunes, in the left pane, you'll see your iPhone listed under "Devices." Click on it, and in the main window, you'll see a bunch of tabs, including "Photos." Read the options listed, and it should be self-evident.
If that's not what you're trying to do, please be very specific in your request.
