You just uploaded a few images to you blog, and notice that the thumbnails cut off the heads of them, 
here is a tool to specify exactly how you want your thumbnails cut, you can zoom in and drag the thumnail 
area to the position that you want. 
This tool is even more useful in combination with theams and plugins that use of thumbnails.

Reposition Thumnails

A pluggin for the moments when the center of the picture wasn't that good as thumnail, so you can avoid cut of heads in yout thumbnails.

WordPress automatically creates multiple copies of every image you upload in different sizes (thumbnail, medium, large, and more). Over time, this wastes a significant amount of disk space, especially on large sites with thousands of images.
Imadero scans your media library, finds all auto-generated thumbnails, and removes them safely. It also updates all references in your posts, pages, and metadata to use the original image instead.
<h4>Features</h4>
<ul>
<li>Scan your media library to find all auto-generated thumbnails</li>
<li>Preview how many files and how much disk space can be freed before deleting anything</li>
<li>Delete all thumbnails in batches (safe for large sites)</li>
<li>Rewrite all database references (posts, meta, options) to use the original image</li>
<li>Prevent WordPress from generating thumbnails on future uploads</li>
<li>Handles serialized data safely (works with Elementor, Divi, WPBakery, and other page builders)</li>
<li>Handles Gutenberg block attributes (sizeSlug, CSS classes)</li>
<li>Removes WordPress -scaled images and restores the original</li>
<li>Batch processing prevents timeouts on large installations</li>
<li>Works with WooCommerce product images</li>
</ul>
<h4>How It Works</h4>
<ol>
<li>Go to Tools > Imadero in your WordPress admin</li>
<li>Click Start Scan to find all auto-generated thumbnails</li>
<li>Review the results: number of thumbnails and disk space used</li>
<li>Click Delete Thumbnails to remove them and update database references</li>
<li>Optionally enable Disable automatic thumbnail generation to prevent future thumbnails</li>
</ol>
<h4>Important Notes</h4>
<ul>
<li>Always create a backup before running the cleanup</li>
<li>The deletion process cannot be undone</li>
<li>WordPress will automatically fall back to the original image where thumbnails were used</li>
<li>The plugin works per site on Multisite installations</li>
</ul>
