🎨 Grid Overlay Style
Grid overlays add a visual indicator to every thumbnail in the WordPress Media Library grid, showing whether a file is in use or unlinked without opening the file.
Choose from 14 styles ranging from subtle colour tints to bold glow rings. The Used and Unused colours are fully customisable with hex colour pickers in the Overlay Colours section in Settings.
Overlays are applied via CSS classes injected into the Media Library page. They have no effect on your site’s front end.
