AJAX Thumbnail Rebuild
AJAX Thumbnail Rebuild allows you to rebuild all thumbnails at once without script timeouts on your server.
By submitting this form you agree to our Terms & Conditions
AJAX Thumbnail Rebuild allows you to rebuild all thumbnails on your site. There are already some plugins available for this, but they have one thing in common: All thumbnails are rebuilt in a single step. This works fine when you don’t have that many photos on your site. When you have a lot of full-size photos, the script on the server side takes a long time to run. Unfortunately the time a script is allowed to run is limited, which sets an upper limit to the number of thumbnails you can regenerate. This number depends on the server configuration and the computing power your server has available. When you get over this limit, you won’t be able to rebuild your thumbnails.

Best option if looking for Regenerate Thumbnails
By 
It did what Regenerate Thumbnails can't.
Has this plugin been abandoned?
By 
Wordfence is giving 'abandoned' warnings since there have been no updates in three years. Excellent plugin though.
So nice
By 
Nice plugin, very useful, efficiency top.
Make it automatic for every new photo or drawing in medias, it will be giant !!! ;)
Only one that worked in my situation
By 
My site has 7600 images, no other regeneration plugin would come close to finishing the process. This did the trick! Even though it hasn't been tested with the latest three updates of WordPress, it ran perfectly fine. I hope the developer keeps this one alive. It saved me! No other plugin would work in this situation.
Word of caution as stated in the description. Do not close the window, or allow your computer to hibernate. If you have a lot of images, leave the window open, turn off sleep mode in your control panel settings and play movies so images dont burn into your screen.
Thank you so much! I can't stand bloat on my server. This really did its job. and it was a big job.
Great Light Plugin

This plugin works great, big thanks to the developer.
Perfect

Very useful, works perfectly with WordPress 5.0.3. A big thanks to the devs :)
Great!

A great plugin. Look at it from a developer perspective. Would be foolish if for this plugin a low rating!

Doesn't really work
By 
I tried this repeatedly with "grayed-out" photos in my media library. Occasionally it worked, but mostly they remained "grayed out."
In contrast, "Regenerate Thumbnails" works brilliantly.
Best of the Best! Must Have!!!!
By 
This is one of the must use plugin for any WP site. I've been WP developer for last few years and have created more than 200+ themes but not a single has been without this plugin. You can also rebuild individual image from media. This is best and works just perfect!
