3D FlipBook - Image problems

I am having constant image issues

i) can't select multiple images to populated a book - only one at a time (why) how it fix.

ii) sizing and editing problems. How can I make the many different proportion images I have fit page with out distortions?

iii) very little tutorial help with images on your support pages - (Seems like only PDF books get clear simple direction with video example. One example claiming to be a guid for image only books is seemingly only a PDF magazine version - which is of no help)

iv) I wonder can this plugin actually provide me with an simple image based flip book with some blank pages some text pages and control over the sizing problems mentioned.

I hope this is clear and look forward to the next step.
