Image sets: sizes in brackets and one-word set names

Old picture groups split every image into a release (the reset's first
hour: 583k releases, 447k of one file; a.b.pictures.erotica.high-heels
262k): "Aletta Ocean - \"100628-035.jpg\" yEnc [347K]" kept its size in
the remainder, and "Corie - \"2877-041.jpg\" yEnc [290K]" named its set
with one word, which namesRelease (two words) refused, so the image's
own name keyed it. Sizes like [347K] (and a cut-off "336573 byt") are
removed; for images a one-word subject (3+ letters) names the set. On
100k high-heels articles: 4,509 releases -> 192. Both implementations;
tests; fixtures identical.
