There are five types of figures— image, file, table, code snippet, and video. Each type offers a dedicated input form for easy data entry, and yet allows you to add common attributes such as caption and figure label. Once figures are inserted, they are numbered appropriately, can be cross referenced from text, and a table of each figure type is generated automatically.

The Figures tool in the Content Editor allows you to add code snippet, file, image, table, and video. Each figure type has different forms for adding content, but shares a common set of fields such as caption and figure label.


When you upload an image to insert as a figure, Lacuna Books automatically generates three dimensions of the same image so that you don't have to resize them manually. Also, enter meta data such as credit detail and URL so that they can be displayed appropriately next to the caption.

Upload a document file (.zip, .doc, .pdf, .txt, etc) to insert it as a file attachment.
