I took this picture, from my iPod, of an iPad showing off my portfolio. It looks amazing. The images are actually sized perfectly for this device. But there was something weird. All the images in the night album, and the occasional other image won’t show. I get the blue image not found icon. Very weird. I wonder if they are exported with some weird settings. Not sure how that happened.
If you want to get a rough idea of what your site would look like on the iPhone, check out iPad Peek. It doesn’t show the broken images like the iPad did, but it will give you a sense of size and how your content will fit. Just enter your site in the address bar at the top.
