Unable to rectify image clarity issue that the site is facing. I've included screen videos, if you slow down the playback you'll see that a clear sharp image is visible (when the Safari browser dimensions are being adjusted) but within split second, the image is blurred. This is happening at www.zuriador.com (Prestashop version 1.6.0.7) where ever product images are being called, starting from the product listings page right through to checkout, on all Apple devices (desktops, laptops, phones and tablets). The sharpness is worst on the iPhone.
