Hi. I had the same problem.. there were three girls in Layla's litter and since i was 9 hours away from the breeder i had to pick just by picture.. when they were only 2 weeks... very difficult! i asked about their personality.. but she said it would be weeks until she'd be able to tell.. since all were very healthy i just went by who i thought was the cutest
which was also IMPOSSIBLE.. you might want to take a drive to see if one sticks out at you.. but it hink it is very early to tell based on personality! good luck!
