I would like my mobile variant to have the option of retina images for the devices that might need it, but have my main page for desktops without retina.

I use photo popups and want to restrict the width to about 900pix on desktops. But when exporting the site the images on my desktop have the arrows at the bottom right to see it at full resolution (1800pix).

Is there a way to prevent this from happening?

Thanks!
