How to Use the Image Gallery

The image gallery is one place to manage every image in your project. Organize your library into folders, drag images where you want them, search the whole project, set alt text, and see exactly where each image is used. To place and adjust images inside your manuscript, see Add Images.

Organize Your Library with Folders

The Folders panel on the left holds your project’s folders. Use them to keep a large library tidy.

  • Create a folder. Click New folder, or right-click a folder and choose New folder inside to nest one within it.
  • Rename or delete. Right-click a folder to Rename or Delete folder. Deleting a folder does not delete your images: its images and any folders inside it move up to the parent folder.

Above the images, a breadcrumb trail (for example, Library / Photos / Nature) shows where you are. Click any part of it to jump back up.

How do I move images into a folder?

Drag one or more images onto a folder to move them in. You can also select images, then use Move to… to pick a destination. To nest folders, drag a folder onto another folder.

What are the Smart folders?

Below your own folders, Smart folders gather images automatically. You cannot edit them, but they are handy for cleanup:

  • Missing Alt. Every image that still needs alt text.
  • Unused. Every image not currently placed in your book.

Find an Image

  • Search. The Search whole project… box matches by file name and alt text.
  • Sort. Sort the library by Name, Date added, Date updated, or File size, in either direction.
  • Views. Switch between grid sizes (Very small through Large) and a List view that shows more detail per image.

Select Several Images at Once

  • Cmd/Ctrl + click an image to add it to your selection.
  • Shift + click to select a range.

When more than one image is selected, a bar shows how many are selected, with Move to… and Delete for the whole group.

See an Image’s Details

Click an image to open the Details panel. It shows the file name, which folder the image is in, its Alt text, its Properties (Dimensions, File size, and, for print, an estimated PPI with a recommended size for sharp full-page printing), and where the image is used.

How do I set alt text from the gallery?

In the Details panel, type a description in the Alt text box. Alt text helps readers who use a screen reader, and a badge shows whether it is Set or Missing.

Where is this image used?

The Details panel lists Used in [number] sections. Click any location to jump straight to it in the editor.

Rename an Image

Right-click an image and choose Rename. You edit the name only; Lacuna keeps the file extension for you.

How do I delete an image safely?

Right-click an image and choose Delete, or select several and use Delete in the selection bar. If an image is in use, Lacuna lists every place it appears before you confirm, then removes it from each of those spots when you delete it.

Undo a Mistake

The Undo and Redo buttons (or Cmd+Z / Cmd+Shift+Z) reverse changes you make in the gallery, like moving images, renaming, or deleting a folder.
