You can sync music and photos to your iPhone by connecting the phone to your computer's iTunes - if you don't have your music in your computer's iTunes library, and if it's in a compatible format, then you can add it via File > Add To Library.

Photos aren't added to your iTunes library, iTunes is only used as a tool for syncing them to a device.

You will need to sync all the photos that you want on the phone together in one go as only the most recent photo sync remains on the phone - synced photos can't be deleted directly on the phone, instead they are deleted by not including them in the next photo sync.
