Images that cannot be posted in an online forum due to improper content. Often these are part of a series of pictures, with a "teaser" picture featuring a "PG-rated" pose. The unposties are the "R-rated" or "X-rated" versions.
A forum member posts pictures of his fully-clothed ex-girlfriend and mentiones he has some "unposties" available. Other forum member request that he sends them a link to these in a person message or email.
