Images truncating at bottom

Hi,
I’m having a issue with my Flipping Book Plugin. The images are getting truncated at the bottom. I have created multiple books with different heights, but in all of them the image gets truncated at the bottom. Is there any limit to the height of the flip book?

I have created a test page where I show the 2 flip books I created with diff heights and also the original image to show the truncation.

Any help is greatly appreciated….
