AFAIK the default behaviour when chosing a variant on the product page is, that the images is also changing to the variants picture.
It used to work in my shop, but it stopped working somehow and I don't know why. I tried to mimic this on my test installation, but it is working there.
Is there a configuration setting, which sets this?
Looking for some help to get this feature working again or at least how I can debug this.
Thanks!
