Same issue discussed here
I agree people dont want to see metadata on dancing bananas or little robots (so they wont click on it) but they might want to check out a close up view of a chart, a UFO sighting, or something (and will click it).
How about a threshold that let’s the little bananas/robots and other images coexist? Just doesnt seem very Discoursey on small devices the way it is now on mobile with default no zom. Maybe not so easy that the team should drop everything.
BTW, I really like the way images get lightboxed with the slide show arrows. I am assuming those edge case images that are not light boxed get left out. At least there wont be any bananas or robots 
but that’s what the threshold is for.
