A Flash Flipbook from Supplied Files is for clients who are supplying complete pages to be assembled into a Flash Flipbook. For example if you already have a catalog designed and want it to be available online, or you are an author and have completed pages of your book and want to turn it into a flipbook for your site visitors to browse online.
You can use one of the backgrounds as shown in the example, a solid color, a color gradient, or an image you supply.
