Description
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.

FAQ
-
Does it affect the frontend?
-
No. The plugin only loads its assets on selected WordPress admin screens.
-
Which media types are previewed?
-
Only image attachments are previewed. The plugin ignores common non-image attachment previews such as video, audio, application and document files.
-
Why does the preview wait before appearing?
-
The delay avoids noisy previews while quickly moving through a media grid. You can change the timeout under Settings Media.
-
Can I change the preview size?
-
Yes. The maximum preview width can be changed under Settings Media in 100 pixel steps from 300 to 800 pixels. The default is 500 pixels.
-
Does it download original full-size images?
-
The plugin prefers available intermediate image sizes such as medium, medium-large or large. If no suitable attachment data is available, it can fall back to the currently displayed image URL.
-
Does it create database tables?
-
No. It stores only WordPress options for the configured hover delay and maximum preview width.
-
What happens when I disable the plugin?
-
The hover previews and Media settings fields disappear. Existing media items and WordPress media data are not changed.
-
The WordPress user “nicmare” vibe coded it. Means he had the idea of the plugin and uses AI to craft the code.
