Mind you, this version is forum-compressed so it only contains 1 million pixels, whereas the number of colours typically codable or displayable on a standard monitor using standard software is upwards of 4 billion. (256×256×256). Maybe the original image has 4 billion pixels.

eh whuth 256 * 256 * 256 isn’t even 1/8 of 1 thoumillion let alone 4 million million
