I still think the right side orientation for photos is better than the left, based on what I call the Ingrid Bergman principle. In Casablanca, the director put Ingrid Bergman on the right side of the screen whenever possible, since Westerners usually start looking on the left and rest on the right (and she’s a lot better looking than Humphrey Bogart). Likewise, most people are right-handed, so the good stuff, the clickable stuff, should be on the right too.
