For anyone in the process of creating their own informational product, I highly recommend using the 3D E-Book Cover Generator from 3d-pack.com.
Not only does it create the awesome reflection effect for your E-book cover, but you can rotate the image any way you want and the on-page Flash will render it to either a gif, a jpeg or a png image for you.
Creating each side could not be easier. Simply upload an image for the cover, the top, the side (and optionally the back, if you so choose) and voila -- you have a beautiful fake image for your e-book.
I was able to create this e-book in less than 10 minutes in order to demo it here:
Sure, you might notice that I could have spent a lot more time making it look fancy but I just wanted to show you how powerful this free online tool is. Here are the three graphics I used:
I just uploaded each image to the corresponding areas and within ten seconds, I had a beautiful E-book graphic. Could not have been easier.
