Avram, I’m against pictures too, for both tznius reasons, and the fact that it becomes a disappointment.
Being picky about looks, in itself, isn’t a big chisaron; everyone has a different teva and must combat the yetzer hora that they’re given. Women aren’t as visual. Telling a man not to be picky is just setting him up for failure.
I agree that a man shouldn’t be looking at pictures, if they must be given, they should be a normal picture shown to the boys mother, only if the boy has specific hakpados.
