WhatsApp is a key medium for the spread of news and rumors, often shared as\nimages. We study a large collection of politically-oriented WhatsApp groups in\nIndia, focusing on the period leading up to the 2019 Indian national elections.\nBy labeling samples of random and popular images, we find that around 13% of\nshared images are known misinformation and most fall into three types of\nimages. Machine learning methods can be used to predict whether a viral image\nis misinformation, but are brittle to shifts in content over time.\n
