"same" means that it was an rsync backup and the rsync method found that the
file was identical to the same file in the reference backup and created a link
to that.
"pool" means that the file was transferred (possibly as an rsync delta, so
that does not necessarily mean a lot of data has crossed the network) and then
found to exactly match a file already in the pool. A link was created to the
pool file.
I'm not sure what happens when rsync detects an attribute change. My guess
would be that that leads to a "pool". Basically, the effect of linking to the
file in the reference backup vs. linking to the pool file is identical
(assuming the file in the reference backup *is* a link to the pool file, i.e.
that linking works and was working when the reference backup was taken).

So would I. Then again, my experience is that photos tend to be changed by
viewing programms when you modify EXIF tags, for example (perhaps by adding a
comment, changing orientation ...) - actions that at least I don't remember as
active changes of the photo. Then again, such a modification is unlikely to
yield a file already present in the pool ;-).
You could always restore the file marked "pool" from that backup and from the
reference backup and try to find out what the difference is.
I believe the web GUI also includes a timeline for a directory, where you can
see which files changed when ...
Hope that helps.

Holger
