flopping

“Flopping” is the left-to-right reversal of an image (reproducing it as a mirror image of itself), something that is sometimes done to photographs that don’t have clear “right-way” things (like words) in them.

Flopping a photograph always disqualifies it from P2, P7, and from TTG, regardless of how or why the flopping is done, regardless of how it is labeled and presented, and regardless of whether viewers would notice.
