In the mobile devices the photo of my products looks very small, in the thumbnail of the other combination it looks in its correct size, but both in the main image and if you open the photo in full screen, it looks much smaller. I attach a photo.
Hi,
If you just want to change the mobile, you can change the medium_default_2x, that is for mobile only. the “large_default” is for desktop, and the “large_default_2x” is for mobile, you can change it.
Best regards.
