Pictures Of You, Pictures Of Me, Crypto Steganography
summary
Friend sends Buffy Babylon 5 and Firefly images that actually carry hidden text, decoded by extracting the least significant bit (and sometimes the two least significant bits) from each pixel, grouping those bits into bytes and doing ASCII extraction to read the payload. Messages before the 2018 Olympics taunt Canada and curling ability, after the Games they repeat the numeric score by which the US won gold, so the steganography decoding works and explains the 15 year rivalry twist.
