Using Lightbox, you can set the linked images in your webbook to open within a chapter webpage as a pop-up.
To enable this setting from your book’s dashboard:
- Click Appearance
- Click Theme Options
- Click Web Options
- Check the box next to Enable Image Lightbox
- Click Save
When Lightbox is enabled, all images linked from your book will open in a lightbox. This applies to thumbnail images linking to larger versions of themselves, as well as text hyperlinks linking to images.
