Hi again.
I figured it out. The plugin WooSwipe conflicted with the woocommerce image zoom. I used the plugin Woocommerce Product Images Slider instead and it works perfectly.
Hi. Thanks for the answer.
It doesn’t work on my site, but it works as it should on the demo site you wrote.
The url is http://www.f-sport.dk.
Is there a size the image should be to work properly?
