Social media provides an easy and ubiquitous means by which individuals can curate and share their personal experiences while also interacting with their friends, family, and the world at large. One means by which individuals can craft their personal past via social media is through their personal photographs. However, psychologists are only beginning to appreciate the mnemonic consequences associated with sharing personal photographs on social media. The aim of this manuscript is to distil the relevant, psychological research examining the mnemonic consequences associated with photography and sharing personal photographs on social media. To this end, we discuss how a psychological approach to memory has evolved from an individualist perspective to one that is beginning to appreciate the importance of a memory ecology. We then turn to photographs as an important component of one's memory ecology and how the act of photography and sharing photos on social media may have important consequences for how individuals remember their personal past. We then end with a discussion surrounding pertinent avenues for future research. We advocate that, moving forward, psychologists should better appreciate (1) the collective nature of social media, (2) an individual's memory ecology, and (3) the mnemonic consequences associated with social media silence. In addressing these issues, we believe that psychologists and memory researchers, more generally, will gain a fuller understanding of how, and in what way, personal photographs, and the act of sharing them via social media may shape the way individuals remember their personal past.
