I want to show some people what an iPad app could look like and need to create a mockup for this. What I need is the ability to have a custom icon on the iPad screen - ideally I have control over the look of the icon and its name. When you tap this icon it displays a fullscreen image (which I'll create in Photoshop). A swipe or click takes you to the next or previous fullscreen 1024x768 pixel image. Ideally rotating the iPad would bring up an alternative image so that I can create dummy application views showing what the portrait and landscape versions would look like. Maybe there is an app that can do this or maybe it can somehow be done with web pages that go fullscreen. Any recommendations would be appreciated.
