Media Library Thumbnail Enhancer Plugin

Makes media library thumbnails match the WordPress thumbnail size or allows you to choose a new size in Settings: Media (or hard code a custom size named ‘mte_thumbnail’).

Also replaces the default “Crystal” file type icons with smoothly scaling SVG icons that better match the WordPress 3.8+ design.

1. Upload the plugin folder to the /wp-content/plugins/ directory or install via the Add New Plugin menu
2. Activate the plugin through the ‘Plugins’ menu in WordPress
3. Optional: Enter a media library thumbnail size under Settings: Media
4. Optional: Define a custom size called ‘mte_thumbnail’ in functions.php

1. 

   Without the plugin active

2. 

   Using the default 150x150 WordPress thumbnail size

3. 

   Using a somewhat ridiculous 600x600 thumbnail size

Is there an options screen where I can set a custom thumbnail size?

Yes! Just go to Settings: Media and look for “Media Library Thumbnails”.

Note that this will not appear if the size has been hardcoded (see next FAQ).

Is there a way to hardcode the custom thumbnail size?

To set a custom size, add the line below to functions.php (or a plugin) and adjust the dimensions as needed.

add_image_size( 'mte_thumbnail', 300, 300, true ); 

I chose a custom thumbnail size. Why aren’t the thumbnails appearing at that size?

You may need to rebuild your thumbnails:

Or install WP_Thumb so they can be generated on the fly:
