Everything Lightbox does

Your library

Track a folder and it appears in the sidebar with its subfolders under it. Collect folders from anywhere into groups you name. A folder with subfolders opens as a row of covers, one per subfolder.

• ⌘Otrack a folder
• ⇧⌘Nnew group
• ⌥⌘Rreveal in Finder
• ⌥⌘Ccopy path

The gallery

Images sit in dense rows that fill the window, each one complete and uncropped. Drag the slider to resize them, show or hide filenames, and sort by name, date or size.

• ⌘Ccopy the selected images
• ⌘Rrefresh

The viewer

One image at full quality, with its size and format in a slim bar. The neighbours load ahead of you, so the arrow keys never wait. Choose a charcoal, black or neutral gray background.

• Returnopen
• ←→browse
• escback to the same spot

Stars and favorites

Star the pictures you like, then show only those. Stars are kept with the folder, so they travel with it. Favorite folders sit at the top of the sidebar.

• Fstar
• ⇧Fstarred only
• ⌘Dfavorite a folder

Compare

Select two images and compare them. Flip swaps one for the other in the same spot. Slider puts them on top of each other with a divider you drag.

• ⌘click two images
• Ccompare

Split

Place vertical and horizontal lines on an image and Lightbox saves each piece as its own file, next to the original. You choose whether the original stays or goes to the Trash.

• Ssplit
• VHswitch direction
• ⇧no snapping

Tidying up

Delete images or a whole folder, rename a folder, or stop tracking one you no longer need in the sidebar. Every one of these asks first. Stop tracking removes only Lightbox's thumbnails, never your images.

• Xdelete
• ⌘⌫stop tracking
• ⌘Zundo

Staying in step

Rename or move a folder in Finder and Lightbox follows it. If it can't, Locate lets you point to the new place. Folders on a drive that isn't connected stay in the sidebar, dimmed, until the drive is back. Returning to Lightbox checks the open folder for new images.

Settings

Two window styles, the viewer background, how much memory thumbnails may use, and whether Lightbox reopens your last folder. Maintenance lists every folder's thumbnails with their count and size.
