For me, face pics aren't crucial.
I know that not everybody would agree with that, nor with what I'm going to put next. What I look for in a Profile are the following: the right age-range for me [late 30s/early 40s in pro$$i£ years]; ideally no more than £100 p.h.; and most importantly for me, a Profile which gives some indication that the WG has probably written it herself and gives a bit of a clue to her personality.
Attractive face pics are the topping on that particular cake.
