[NTLUG:Discuss] Photo Organizer

[techvista]

I am looking for what you consider to be the best Photo Organizer (under 
Linux, of course). Criteria:
1) Tags - can associate various tags/labels that let you do searches. 
Ideally, allows you to select a group of files to add the tag(s) to.
2) Can understand EXIF and other meta data (specifically must know what 
Canon 20D generates, which should be standard)
3) Knows how to handle embedded jpg inside RAW files (IIRC, Canon 20D 
can store that way)
4) Does not copy files into it's own area/DB.  Unless you can bring up a 
very good reason for this, I consider it a waste of space.
5) Fairly fast to browse through sizeable thumbnails
6) Means of marking favorite pics (subset you consider best.  I take a 
lot of pics and don't like to delete much...)
7) Knows how to display photos in correct position (portrait / 
landscape) using info stored from camera

Nice to have:
8) auto tags with timestamp found in EXIF metadata so can do searches 
based on date
9) drag/drop organizing of actual files.   I still prefer to have a dir 
tree of year / event (such as Christmas) / [sub-event] instead of one  
multi-gig dir of all pics.
10) It is possible that in the near future I'll get a Mac to do all of 
the photo stuff.  So, it would be nice to make it easy for the Mac to 
utilize the tag set.  At least be able to import it.
