I am setting up product images and I noticed that there are not displayed correctly in google chrome. When I have one featured image and couple images in the gallery in google chrome the main image is moved up and it is not visible.
On the other hand, the same page is displayed correctly in Safari.
Please let me know what I am doing wrong. Maybe I messed up some options.
What is the correct size for a single product image?
It seems to be some similar problem regarding your HTTPs configuration. Your images are loaded with HTTP instead of HTTPs and that is why don’t work well https://gyazo.com/f16e31aacc3a6b7de6ff892ee6876161
There is no required size for product images and it depends on your own images aspect ration. You can configure it in Appearance -> Customize -> WooCommerce -> Product images.
