how do I do a page curl effect on two corners of an image

Question

I'm trying to do the effect shown above in my app, but am unsure what the best practices are. The effect I want is the curled bottom corners of the outer picture frame.

Is it better to:

1. use a page curling library like: XBPageCurl
2. use images
3. use some other effect
