Waldo's challenge

To download all image files just execute ./exif.py. It'll save the image filename and the exif tags, as key/value pair respectively in a sqlite3 files.db.

The schema of the database is the following:

create table photos (
id integer primary key autoincrement,
filename text not null,
exif text not null);

So, if you need to query the exif value of a file, you just have to provide an image filename in the where clause of a select sentence.
