So you could just check if the frame i is similar to the frame n-i?

  The idea is that frame 0 is similar to frame 0, and also that frame n is similar to frame n. (The resulting gif is 2n - 2 frames long.)

    I'm missing something. I don't really understand the first part of what you said...

      You just play it normally once, then in reverse. Then it loops around.
