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 !!!

The site is experiencing technical difficulties. Please check your site admin email inbox for instructions. Sorry but this doesn't work for me either, I get the message above. I can see that this error was labelled as "Resolved" below: Unfortunately it is still occurring. I'm using 'Storefront' theme by WooCommerce. I was really hoping this would fix the image fitting problem I have but sadly it didn't work 🙁 Regards Warren UPDATE: Nabil the developer replied very promptly with a helpful solution to the problem below: Did you read the FAQ section? Probably the PHP Fileinfo extension isn’t enabled on your server. Please enable it or ask your hosting provider to do it for you and try again. There are more than 1000 active websites using the plugin, and it should work for you too. I had already found an alternative workaround so didn't actually use this plugin in the end but I'm sure it works fine.
