Analyzing this stuff, we found that most of the pictures on OkCupid were of recent vintage; site-wide the median photo age at upload was just 92 days. However, hotter photos were much more likely to be outdated than normal ones.
As you can see, over a third of the hottest photos on the site are a year old or more. And more than twice as many hot photos are over three years old (12%) as average-looking ones (5%), which makes sense because people are more inclined to cling to the pics that make them look their best
Another useful (if somewhat unorthodox) way to take in this graph is to follow the horizontal gridlines. If you trace out from "20%", for example, you can see that 1 in 5 average-looking photos is at least a year old, meanwhile, among the hot photos, nearly 1 in 5 is at least two years old.
