I'm trying to support retina on my site, so I set up a 2x image style and a 2x responsive image style. Now the generated HTML for images looks something like:
<img
srcset="/sites/default/files/styles/2x/public/2019-01/foobar.jpg?itok=H_4_Z44r 1926w"
sizes="2x"
src="/sites/default/files/2019-01/foobar.jpg"
typeof="foaf:Image" />
This image was already uploaded to my site when I made the change to support 2x images, and I noticed that it actually copied the original image over from /sites/default/files/2019-01/
to /sites/default/files/styles/2x/public/2019-01/
.
My problem now is that I'd like to update the 2x version from the authoring interface, but I can't find anywhere where I can upload my 2x version. Is this possible?
