Image sets: keyed by set without words around them; px, ImageVenue, spaced repeats

- An image whose subject has no words ("##[ "diana-040-001.jpg" (01/68)")
  is keyed by its set, not its name without numbers: a poster's 263 diana
  sets were one release of 17,808 images.
- imageSet strips "-2048px" and ImageVenue's "_123_244lo", and reads a
  spaced suffix ("she has sensual legs 172 _ 172") as one.
