This last week the This Week in Photography (TWIP) Podcast had an interview with John Philpin, the chief marketing officer of LiveBooks. The subject of the interview was a discussion about the fact that photographers and other creative people need to have websites viewable on iPhones and iPads. John explains why LiveBooks has decided to support iPad and iPhone users and how they do it.
LiveBooks is a high-end web hosting company for photographers and other creative business people. I don't think you can do much better than a LiveBooks website. One interior photographer that you may know that has a LiveBooks website is Scott Hargis. I think Scott's website is a great example of how Flash can be used to create a great portfolio viewing experience. On a PC or Mac the site delivers a great experience, yet if you hit his site with an iPhone or iPad you don't get a little blue rectangle; you can still see his portfolio.
The best part of having a LiveBooks site is that you have to do little or nothing to make your site accessible to devices that don't support Flash. After LiveBooks did their upgrade with this functionality it just works. LiveBooks creates a separate site for iPhone users and a separate site for iPad users in addition to the main Flash site. Since there a million iPads a month being sold this issue is not likely to be going away soon so it will become more important for photographers as time goes by.
