Here's some code I wrote to read/write weather data in jpeg image
headers[0].  It uses the Python package pyexiv2.  Re the ops issue, I
think that it's inevitable that the file names will need to be parsed
to harvest the keywords/tags from them.  If the tags aren't stored in
some kind of database, even a flat file, that parsing will need to be
run on each search.  There are lots of handy command line tools to
help automate this but I'd do it with Python and sqlite.
