All images now stretched, with recent update

Hi there 🙂

Firstly, I'd like to say thank you for providing such a fantastic free version of your plugin - the charity site that I maintain doesn't have the resources to pay for plugins, so we're very grateful for your brilliant free version.

I've never had a complaint at all until today when I ran the latest update for the Post Grid plugin and found that all the featured images that pull through from blogs to create the images in the grid itself are now dreadfully skewed. Is there a simple solution for this, please?

Thank you,
Rosy
