Online photo sharing is a popular activity. However, users may share images via a photo sharing application or website, or via different messaging applications. When different users share photos with the same group via different mechanisms, the photos are not available to users in a single, convenient location. This disclosure describes a chat bot that can be invited to join a chat conversation conducted via different messaging applications. With user permission, the chat bot automatically retrieves images (photos and videos) shared in a messaging conversation and adds the images to a shared album or folder in a photo sharing application. Members of the conversation group are provided access to the shared album.
