Reply To: Problem with shrinking image.

Hello,

Actually the image does not shrink. You have set cropping for the main product page in Appearance > Woocommerc > Product image. And variation image is shown as it uploaded without cropping. That is why it looks like image is shrinking.

You can solve the issue by either disabling cropping for the main image or uploading all the images in the same aspect ration configured in Appearance > Woocommerc > Product image.

Best Regards
