Hi Bob,
I'm not sure about your 'spanner in the works' comment but a request to the forum's Admin Team could have any image removed.
Most old street pics on the forum have been copied from somewhere, either from books or from sources on the web. I only know of two or three threads where the old street pics were actually photographed by forum members. I myself don't scan from books etc.
This particular 'fun' thread started with pics linked to existing forum pics but changes of forum software broke the links so I edited or removed them.
With reference to quoting sources, see examples in post#2482, although I have no idea where the tram pic came from. I've seen it in various places on the web. I coloured it for fun (reminded me of childhood) but I'm probably more interested in the technical aspects of how computers do it. I did wonder why the tram had no adverts on it!
If anyone has not seen it, a quick route to 100 pics in the thread
