I believe this is called 'Image proxies' I did a quick search and found this description http://www.deneba.com/cvhelp/command/image_proxies.html Did lots more searching of the mailing list archives and if I'm reading this correctly proxies are already being used for things like thumbnails and previews. http://lists.xcf.berkeley.edu/lists/gimp-developer/2002-April/006814.html Dave CC'ed the developer mailing list so anyone who is interested should read the responses there too. http://www.mail-archive.com/gimp-developer%40lists.xcf.berkeley.edu/msg06802.html Sincerely Alan Horkan http://advogato.org/person/AlanHorkan/ _______________________________________________ Gimp-user mailing list [EMAIL PROTECTED] http://lists.xcf.berkeley.edu/mailman/listinfo/gimp-user
