Thanks for the replies. I didn't found problems with the permissions. They were all set, for all the albums, as visible for everybody, and modifiable by admin.
I did found a workaround, though. It seems the problem is the following: I upload new photos to a "temporary" album, which is hidden. That way I can work on how to organize the photos in sub-albums, and then I move the new photos and possible new albums to the visible albums. I notice that if I move a sub-album from this hidden album to a visible one, it remains invisible. If I move a sub-album from a visible album, it remains visible. So, annoyingly, sub-albums silently inherit the hidden attribute, and, at least in the woody version, this cannot be unset, as the <<Edit Album>> options only show the "Hide album", not the "Show album". The only solution I've found is to make the temporary album visible, create duplicate versions for the problematic sub-albums, and then move the new versions to the desired locations. This does not make me happy because too many albums are involved, and I didn't notice until today. The problem only seems to appear with albums. Individual pictures move from a hidden to a visible album remain visible, which is why I didn't notice before.
