  AFAICT the spec does not exclude zero-size images, which would make the smallest image 22 bytes (14 bytes header + 8 byte end marker). Otherwise the pixel in a 1x1 image can be encoded in 1 byte, giving 23 bytes total.

  That's not too interesting and has been covered too many times (e.g. [1], [2]). Maybe it's much more interesting to compare the smallest possible file for a particular pattern like a 2x2 B&W checkerboard.
