I have no interest in further talking to someone who brings up what the article counters with zero counterpoints, and just insists the original point progressively louder.
(Edit: Total comment rehaul to better explain my position, but similar sentiment.)
At least on my instance, the top right hand corner on all thumbnails has a little symbol that shows if it is a "link picture" or an "expandable picture."
The link symbol looks like a box with an arrow, the picture symbol is the generic white outline hills and sun symbol it seems like many places use for images.
Doesn't really answer your question directly, but it might help?
