- masklinn 6y ago> I maintain it’s an odd choice given the availability of alternatives The problem is that the "alternatives" are not reliable: image hosting sites commonly will optimise files by removing ancillary and unknown chunks, losing the data. However as long as they don't rewrite the image data itself (e.g. by resizing the PNG or putting it through a quantizer) the steganography method will ensure the data propagates correctly.
