There is no direct equivalent, but there is the very good (and free) Nokia Multimedia Transfer app from the Nokia web site. This allows iPhoto to import images as if it was a camera (with a USB cable, or handily and wirelessly via Bluetooth). You can also synchronise an album too. You can do the same with iTunes. You make a playlist and it transfers to the phone on request.
To synchronise the contacts, you need iSync. However, this appears as yet unsupported directly by iSync and needs a plug in. A plug in for this phone can be bought, or you can convert a plug in for another Nokia Symbian phone to do the job. This works fine as I've done it with this and some other supposedly non-compatible handsets.
