Picturebag’s down for whatever reason (database permissions or something, according to Jon). Recently made these two pictures because I was bored and feeling nostalgic (and am graying, apparently). Most of these pictures were taken during college, but there are a few from high school and before (and post-college as well). Pretty good spread of clean-shaven to full-bearded (although my face is pretty unchanged since 10th grade), and skinny to muscular to fat.
I like F9 or D6 the two best. Click for convenient wallpaper-sized images.
