#------------------------------------------------------------------------------
#
# Gets meta information about images from the OSM wiki.
#
# Reads the list of all images used in Key: and Tag: pages from the local
# database and requests meta information (width, height, mime type, URL, ...)
# for those images. Writes this data into the wiki_images table.
#
# The database must be in DIR or in the current directory, if no directory
# was given on the command line.
