Map tagging campaign: how to remove the Untagged maps? templates
If the Flickr page for a title includes maps (or ground plans), copy-and-change the template {{UntaggedMaps|sysnum = nnnnnnnnn}} in the line to add a template {{HasMaps|sysnum = nnnnnnnnn}} before it, with the same number.
Once all the map images have been tagged on Flickr, remove the {{UntaggedMaps|sysnum = nnnnnnnnn}} template
If there were no maps, replace the template with the words: no maps
