Here's The First Instagram Photo Ever. Four years ago today on July 16, 2010, Instagram CEO and co-founder Kevin Systrom uploaded the first photo to the app, which was called Codename at the time. This picture of a golden retriever was taken at a taco stand called Tacos Chilakos, and the foot belongs to Systrom's girlfriend, according to a spokesperson for Instagram.
Ever wanted to know what the first ever Instagram post was from your favourite celeb but don't want to scroll through EVERY photo? 1.
