Image sets: a counter in the name ends the set; copy markers, resolutions, _00 go

Each image was a release of its own in: "Set 008  10of63  new0464.jpg",
"202/430  princess-079-058.jpg", "( 098 /500)  002 148.jpg" (the counter
is part of the name: the set is the text before it),
"sexypattycake_0903040445[1].jpg" (a copy's marker), "092_081_2000x1500.jpg"
(a resolution) and "KP0027_197_00.jpg" (a constant suffix).
