oh no these are albums built with fotoplayer I use for an event. The last event they printed the wrong password to all the entrants and so was trying to see if I could just change the password in one of the files without having to rebuilt the gallery.
Not sure about how FotoPlayer stores the password, but rebuilding the gallery should take only a minute or two. The images don't have to be processed again. Just click Make Album - do NOT choose Make All, which actually would reprocess all the images.
