First one....if you have your all your chip images in folders.....you can sync your picture folders to your photo album on the phone using iTunes....probably the best way IMO because you do not need a internet connection to access them.

Second is uploading photos to Picasa....google photo sharing website. With the Google app on the iPhone, you can connect directly with your Picasa account and view photos that way. Internet connection required

Other option I have used is a application called Orb....You download Orb on to your computer, then purchase Orb from the app store ($10) Orb makes it easy remotely connect to your home computer and access files with the iPhone. With Orb I also purchased a TV tuner and I have all my digital cable channels on my phone.

Since we are talking about iPhones...check out a website I made for the iPhone...It is a poker room guide for vegas...still working on getting all the poker rooms on it
