LMDM Media Library Hover Preview adds a small quality-of-life improvement to the WordPress media workflow: hover an image thumbnail in supported admin views and a larger preview appears near the mouse cursor after a configurable delay.
The plugin works in the Media Library, media picker modals and common post editing screens. It tries to use the best available image size from WordPress attachment data and falls back to the displayed thumbnail URL when needed.
The delay and maximum preview width can be configured under Settings → Media. A small loading bar on the hovered thumbnail shows when the preview will appear.
