WordPress 3D Flipbook Embed
The embedded type of Flipbook is the basic and default viewer from DearFlip. These work great on page where the main page about the book or when these is just one book in page. This example is created by using Embed shortcode.
Example: [dflip id="91"][/dflip]
Multiple Embedded Flipbooks in a page
But things change when there are more than one flipbook in a single page. A single Flipbook consume certain amount of time to load and consumes memory. Thus multiple embedded flipbooks will increase that page load time and memory consumption additively.
Embedded flipbooks are best when you have a page specialized for that flipbook. We suggest using one or 2 embedded flipbooks in a page, not more. For more flipbooks in a page use lightbox(popup) solutions.
What changes you need to do?
The default shortcode needs to be updated to popup shortcode by adding type="thumb" or type="button" or type="custom"
