A save cannot be beaten — the bytes are already on the machine — so the page
stops handing over the uploader's 4000px original: each photo is decoded,
redrawn at the size of the box it sits in times the screen's pixel ratio (2x at
most) and only that smaller copy reaches the tag. A visitor who saves one gets
a screen-sized file.
Right-click, drag and long-press are turned off on top of it, and the QR code
card — a link image, not a contribution — is left as it was.
