Update activity
How busy the existing users are, measured as downloads in the last 30 days for every 1,000 active sites. A spike means a new release everyone's pulling; a long, slow decline means an aging user base that updates less.
Release cadence
No release in a yearHow often this plugin actually ships. A steady rhythm is the maintenance signal a single "last updated" date can't show.

Estimated value
What this plugin might earn a year, and what it might sell for. Modeled from public signals; we don't see anyone's books.
Est. annual revenue
Est. acquisition value
No paid tier is visible, so we don't put a figure on revenue or sale value: that would be guessing. The install base is a real asset to an acquirer, just not one public data lets us price. The recent download trend is too spiky to read.

With over 4K images on my site, it’s impossible to get “Regenerate Thumbnails” in Woocommerce to complete. This takes care of it in a couple hours without taking a break. Thank you! Running WordPress 6.8.3 & PHP 8.4

No replies to support queries for over a year so it seems like a dead plugin. hopefully you backup your site before trying this.

This is a great plugin, easy to use and it should be in Core in some way or form. It’s ridiculous that Woo does automatic thumbnail regeneration, but WP Core doesn’t. Thanks for this.

It did what Regenerate Thumbnails can’t.

Wordfence is giving ‘abandoned’ warnings since there have been no updates in three years. Excellent plugin though.

Nice plugin, very useful, efficiency top. Make it automatic for every new photo or drawing in medias, it will be giant !!! 😉 This topic was modified 5 years, 4 months ago by Wabbitt83.

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.
