They don't load for me either, most likely a problem from when we rewrote most of the about.gitlab.com website last year. I'll look into it, I'm also interested to see what it looked like in 2012 :D

EDIT: It looks like the images are attempting to load from an old Wordpress blog which is no longer around, with a quick search I couldn't seem to find anything with similar file names in the current website repository :(
