Please disreguard my previous comment, I was under the influence! :o
I'm glad this important subject has been raised. I wish that there was some sort of device which would allow regular contributers to supress old photos of pubs, especially those that have been refubished. A good example is
http://www.pubsgalore.co.uk/pubpictures/42455/ The previous photo is a good one, but it shows the pub in a state of closure. In some cases, might it be an idea to contant the photographer and ask them if they could supress their own photo? This would be a more freindly approach.
Another angle to looking at poor photos on this site, is that they don't give a good impression of Pubs Galore. Photos don't have to be perfect, but they should at least be a clear image of the pub.
That's me off my soapbox!
