Excellent, works as advertised

I wish I would have tried this before trying some other Regenerate Thumbnails plugin. That plugin ended up making duplicate images and attaching the duplicates to the products. I still had the old images in my folder, but without the thumbnails, and new duplicate ones with thumbnails.

This plugin saved the day. Well, kinda. I still had to rebuild my image folder and reattach all the images to the correct products, but this plugin worked flawlessly when I needed to regenerate the thumbs. My theme and plugins were creating a lot of different size thumbs that I wasn’t using, so I was able to adjust the code to narrow down the thumb sizes that were being made, and this plugin made it easy to test my edits.

Great job and thank you so much for making it free.
