X-Face

X-Face is an optional, in the late 1980s incurred, unofficial header in Usenet articles or emails, which allows, as text encoded in the message a small black and white image, this rider.

Usually represents the X-Face a portrait or logo of the sender of the message dar. It is limited to a size of 48 × 48 pixels and a color depth of 1 bit ( ie a pixel can only be black or white, no gray).
