I am with Old Boots on this one as I will only upload photos that add something to what's already there.
But I don't have an issue with the serial photo loaders as for me the photo date history is one of the big plus points of PG over other sites and for every multiple entry set that adds no value, there's another that provides inside into a pubs changing look.
I always try to get a close up of the pub sign and don't tend to bother with the view unless I can get the pub garden or benches in as well, although I did break this rule once when at a coastal pub as the view included a particularly impressive seagull.
I also have to confess to sneaking into a few of my pub photos and my better half has appeared unknowingly in a few of my interior shots.
