We have to be careful about the definition of "database" here. According to the legal definition of "database" which has been quoted here often enough, any PNG file made from OSM data would qualify as a database, which would render the whole concept of a "Produced Work" totally useless for OSM. Thus we have agreed that we are willing to consider a PNG file to be a Produced Work unless - and I don't find the specific wording on the Wiki right now but I think there was something like this - someone creates the file specially with the purpose of transporting the database through it. In that light, I fail to see the difference between a PNG image that represents a list of bakeries in London (which you and Andy would say clearly is a derived database or a substantial excerpt) and a PNG image with a map of London and little bread symbols where there's a bakery (which we do not want to be a derived database nor a substantial excerpt, or else the whole ODbL Produced Works idea would fall over and be useless - for example we could not mix our map with data licensed under another license).
