Digging further into the meaning of the pictures, I made three categories:

Place - commemorating being at a location, typically with a very nice background where you can see landmarks or more of it than the person

Event - capturing a moment where what was happening is the most important (i.e. being at Pride, or skydiving)

Self - a nice picture of oneself for the sake of being a picture of oneself

More than half were in the Self category; however, the other half was divided between Place and Event. I'm not surprised that Event has more. I think events usually have a purpose which can have more meaning to more people whereas traveling to places requires the person to develop some sort of attachment to it first.
