All these frames can be seen in the first 1 - 1:30 m of the movie Devil's Pass. They are fully fabricated for the purpose of this movie.
Although the movie is more or less hated throughout the Dyatlov community the last frame has become very popular to represent Dyatlov Pass case, and Clark Wilkins in his book "A Compelling Unknown Force aka Six Hours To Live" on p. 144 is using frame №4 with subtitle Rustik Slobodin, which he is clearly not.
