The version of the gallery software I’m using has been updated to v1.3
I’ve not had chance to merge back in my own EXIF preserving changes, so rotations are still decidedly dodgy, but the upgrade was as easy as suggested in the text file, although I do wonder what sort of slideshow is on offer when the default timeout is set to 3 seconds… The sub-album listing is well worth the update though, even if I decide to move onto a less CPU intensive system (still testing the various options).
