We've attended east coast SF cons since 1976 and I can't recall any that had photos. They were pretty much in the The South. But you know, having a photo for an SF con rings a bell somewhere. Maybe. If so, that was THE only one I can think of. Doing photo badges are time and money, generally something neither cons nor attendees have.
It may have been a goofy idea for a theme a con was doing one year.
As a contrast, when I worked for the government, my group co-ran the annual conputer security conference with NSA. This would be the early 90's and we never had more than a name and agency on the badges. Several agencies would buy a number of badges, put generic names on them and a different group from that agency would attend each day.
I attended a day of a Homeland Security conference about two months ago. They had spiffy I.D. computers, but no photos on the badges.
