Museum Cultural Relics Exhibition App Design

The first page is the homepage of the App where you can slide horizontally to see the pieces.
The second page is the detail one where you read. In particular, the picture is folded in a small round button. When you click that small picture, you can always see the big one floating above the texts, just as the 3rd page shows. Tap the blank space to return then you can continue your reading.
The inspiration is to divide reading and exploring the picture into different actions. Instead of sliding the picture away with the texts, you can just click the picture button to check whenever you want to see the picture or at whichever page.
Press "L" if you like and different ideas are welcome:P
