I needed to resize and regenerate my site woocommerce images due to a site layout change. Did not want to do this manually as I have over 500 products. I bought the pro version and initially had some issues getting the images to complete resizing so I contacted support. Cannot say enough good things about Nabil, the author of this plugin!! The issue ended up being a resource issue with my site having too many plugins running at the same time as regeneration which caused the plugin to halt **BUT** Nabil not only diagnosed the issue but after I disabled un-needed plugins he came back around and made sure that all my images properly resized. Images look great, saved me a TON of time, and again can't say enough about Nabil's standing behind the product.

5/5. My customer had loads of different image ratios to deal with in category views. All solutions, except having the thumbs 1:1, fitted and cropped smartly are just not very good. This plugin, with Regenerate Thumbnails, did the trick. Now everything is displayed beautifully. Thank you, thank you. Recommended this to a dev friend the day after I used it, he used it as well. (We both ended up getting the Pro version to leave it on, customers don't care to crop their images on their own tbh) Cheers 🙂

I downloaded the free version and after 3 minutes I bought the PRO version. The plugin is EXCELLENT! For a year I didn't know what to do with WooCommerce photos, because we have 30,000 imported products with different photos. Thank you for this plug and I wish you thousands of sold!

A much needed plug in and very simple to use. In fact now I can focus more on selling than worrying about how to right size and resize my product images. The developer is very proactive in support and his responses and solutions are prompt and always work. Highly recommended !!!
