Hello archivewashington,
Thanks for your interest for the plugin.
The answer depends on your version.
If you have a PLUS or PRO version, you have to create a new book (click on my books & add a new book), then to add your contents by clicking on the icon in the middle :
> with PRO, you manage chapters and assign content (bulk add images) for each chapter
> with PLUS, you directly add your images with the bulk upload system in the books, clicking on “Page Management”
For LITE version, it’s easier, just click in the menu on images, then “add images” specifying the image you want to upload.
A doc is currently ready but in French, don’t hesitate to post on the official forum in order to allow us to answer with screen captures if needed.
Best !
