Another question: why are the originals of the portfolio thumbs and bigsize images larger then they appear on the website? The browser now downscales them which make them not as sharp as they could be…
Portfolio thumbs are @2x size to provide retina support. You can scale them 1:1 but since this is a responsive template scaling will always be seen on some devices.
But it’s true that in case of using 2x size the quality on non retina-screens (which i imagine to be the biggest part of my visitors) is just not as sharp ?
