It is not possible to tell from > the thumbnail itself which file it corresponds to (one way hashing, in > other words). should not be a problem with locally stored thumbs, although another problem would arise: what happens when the originals are deleted or their permissions are changed? now that I think of it, what happens currently with such a scenario? orphaned files in ~/.thumbnails/? I don't know of a solution for this sort of linking, but I wish there was, so that XMP sidecars and other meta files could be linked too (and copied when dragging and dropping the master file). I'm surprised how little the GUI metaphor has changed since the Xerox Parc times. We're still browsing volumes, folders and files hierarchically. OK for a floppy but IMO inadequate for today's media. And IMO OK from a CLI but not from a GUI. I expect a GUI to add usability value. The solution to the specific problem of thumbs is IMO *choice*. Put a .thumbs file at the root of every file system. If it exists, thumbnail all files on that volume automatically. If it does not, don't. The owner of the media (hence root and not user directory) should decide if thumbs are permitted. For RW media this is easily changed to the preferences of the users and for R-only media the author can make the decision at authoring time. I've not tested it, but I wonder how all of those programs that rely on thumbnails react if I chmod 000 and chown root:root my .thumbnails folder? surely ugly, and would not achieve the higher usability that I hope we can achieve together by spinning these idea further. Thanks everybody for the stimulating thoughts. Yuv _______________________________________________ Usability mailing list Usability@gnome.org http://mail.gnome.org/mailman/listinfo/usability
