I ran a somewhat long thread (32 pages) a second time, using the newer vef-imagerescue 1.11, and I noticed that it paused for a long time (minutes?) before its said FINISHED. This is presumably when it was double-checking the files that did not download the first time through. After the long pause, it downloaded an additional 12 files, so the double checking was worthwhile.
Just ran another pic-heavy thread for the 2nd run, this time with version 1.11, and after the big pause, it's downloading many images as duplicates of those already downloaded successfully the first time. Also, the "last modified" dates shown by Windows are not correct; they are dated two or three days ago though I just downloaded them minutes ago. And no, the files were not updated in the posts a few days ago either.

Update: New version 1.12 takes care of this problem. It turns out, I was looking in the original folders, and version 1.11 was creating new folders (explained in the bugfix for 1.12), so the dupes were actually created by an older version, which is why I thought the date of the files was wrong. Hopefully the duping won't happen with the updated version.
