Hi Gals and Guys I have released Displayator, an app for iPhone and iPod touch. As the title says, it allows you to view huge images on your iPhone in their original quality, unlike when they go through iTunes. It works by transfoming a copy of your big image on your computer (using a free app) and then lets you to transfer ithe transformed file to your iPod Touch over Wifi or iTunes file sharing. The biggest images I found are of 30.000 x 1.000 pixel , 14.000 x 14.000 and 20.000 x 10.000. The conversions took a while, but in the end, it scrolls like silk on both my iPhone4 and my original iPhone. More info at http://www.displayator.com You can buy the app from the app store http://itunes.apple.com/us/app/displayator/id438034770?mt=8&ls=1 . It's only $4.99 until I finish and release the universal version.
