How can you tell if a flag is waving from a still picture?

Oh, and look closer. The shadow is there.

(This sort of thing always struck me as a non-starter, anyhow. Why would any kind of conspiracy build an entire moon set, LM, astronauts and technical equipment, and flag...but somehow not have the flag on the same set on the same day but have to paste it crudely in...and how is it the person who "pasted it in" was so good there isn't the slightest visible edge, and the lighting direction is spot on, and parts of the shadow are clearly visible...but somehow they "forgot" to finish painting in the shadow?)

(And then add to this...the flag appears in video. Taken from similar angles. Which means it WAS there on the "set" during one point. So why wouldn't it have been in the stills? Your conspiracy makes no damned sense.)
