An image's post token needs a word in it, not only a size

"01of37 ## Alexi uses strange toys … ## alexis001.jpg (1/1) 57295b": with
the whole text as the name, the remainder is the file's size "57295b", which
229189f took for a post token: 16 sets of 36-37 images became 268 releases.
"MDG005b" has letters in a row; "57295b" doesn't.
