Highly Recommended

1) Works fast. 121 images regenerated locally in 90 seconds.

2) Does what is says.

3) Use in conjunction with the add_theme_support() for 'post-thumbnails' and the add_image_size() function added to your functions.php file.

Developer works for Automattic and keeps the PI current with latest version of WP core. +1.

Take that images, now you're a different size!

It's like having control of all of your friends' weight on a molecular level. Like if you could just imagine all your friends were completely different shapes and sizes, and then after some amount of processing (depending on your server / super power's processing power), they would be those various sizes.

But for images. In WordPress.

This is part of my developer tools kit whenever I run into any problem related to Thumbnail sizes, this WordPress Plugin does rescue job and it never fails. It is very reliable plugin and always does the job!

Thank you Alex for creating such awesome plugin and thanks for making it available at W.org!

[Solved] Stopped working correctly
By , for WP 4.3.1

Update: It turns out that I caused the issue. When I switched servers I forgot to install php5-gd. The weird thing is that there were no errors in the logs.

What @mediadivision says is true, unfortunately after a regeneration run today my "thumbnails" are now the full size images. Unfortunately though, I cannot use a replacement as the theme I'm using requires this plugin. Hopefully it'll be fixed soon.

Messing up the database
By , for WP 4.0

While the plugin does resize the thumbnails as expected it messes up the meta entries of the thumbnails in the database. This behavior results in getting the wrong image urls with functions like wp_get_attachment_image_src. That is a really nasty issue, because at first glance everything seems fine, but a look at the generated html shows that the url directs to the full size image. Very problematic when you want keep the size of your website small.

I recommend using this plugin instead: https://de.wordpress.org/plugins/otf-regenerate-thumbnails/
