Hi Graham,
Thanks for reaching out to us.
1. Please add a custom thumbnail size. Here is a reference from the official WordPress Developer Handbook- https://developer.wordpress.org/reference/functions/add_image_size/#comment-296
2. Then use a plugin called Regenerate Thumbnail- https://wordpress.org/plugins/regenerate-thumbnails/
3. Regenerate all the thumbnails using the plugin.
4. Then the newly added thumbnail size will be appeared here- https://paste.pics/QMNH9
5. Select the newly added thumbnail size from the dropdown box.
I hope this will resolve your issue
Thank You
Thumbnail images are being cropped which we dont want
Graham Saunders
Is there a way to ensure that the thumbnail images show in their entirety and not be cropped. It looks messy when the images are cropped in this manner. All of our product images are in the ratio 1.5 to 1 so the images are rectangular (not square). I have tried adding some custom php code, to not avail. Thanks for your help.
Graham
