I've written a new search script for RGL that lets you list pages without a photo. You can restrict the results:
- by category (e.g. all Jubilee Line stations),
- by locale (e.g. all places in Islington),
- by postal district (e.g. all places in SE16),
- or by location (e.g. all places within 1km of the bandstand in St James's park).
(To restrict by postal district, use the "locale" box; the postal districts are in there. I'll separate them out later today if I get time. Also, the easiest way to find the X and Y parameters for the location search is to find the location on StreetMap, click on the exact location so there's a little arrow pointing to it, and take the "x=" and "y=" parameters from the URL.)
I also added a page explaining how to choose and use photos from Flickr.
