With the ScandiPWA theme, customers are welcome to use the image zoom functionality on product description pages.
On mobile, image zoom is performed via pinch. On desktop - by scroll. For user convenience, the message has been added to an image gallery, with a proposal to scroll.
Once zoomed in, the image will be changed to the originally uploaded in BE allowing to have a higher quality on zoom but not damaging the performance of the product description page.
