I'd like to be able to adjust how much I zoom into a picture using the photo viewer. Adjustable through a menu option.

The different zoom levels could be:
Default (Pre default)
Zoom to Width (zooms so that the picture orients the zoom to width)
Zoom to Height (zooms so that the picture orients the zoom to height)
Zoom to X% (where X is a percentage based on a user adjusted slider, hidden or grayed out when other zoom types are selected)

I've looked into developing this myself, but decided its a bit much for my first project. I don't horde ideas that I can't implement so here it is. Let me know here if you have any questions.

Sorry if its a duplicate request. I tried several search terms and came up empty.
