David mostly doesn't vote
Is that normal???
EXIF info is your friend but failing that, a bit of elimination will probably do the job

Oh, and location, location, location
I love running this comp (actually, I run a couple of others but prefer this one

) and my problem is that I know who submits the pics. It shouldn't make a difference I know but just occasionally there's a lingering doubt that I've made the right decision. It's not helped any by my over examination of everything - like the time the wife and I went on holiday (abroad, in the sunshine). I spent many evenings slaving over a hot spreadsheet, entering all the permutations and giving everything marks out of ten. I must have spent the best part of two weeks, a couple of hours per night, just reaching a decision. The wife casually looked through the brochures for ten minutes and pointed at the very place I had spent hours researching
Sounds like I need a new year's resolution.....
