Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for augmenting an interactive session with images. In one aspect, a method includes generating a first linear arrangement of images captured during an interactive session. The images of the first linear arrangement of images can be arranged in order based on a sequence in which the images were captured. The first linear arrangement of images is provided for display. Selection data specifying a selection of an image of the first linear arrangement of images are received. In response to receiving the selection data, a branch point is created at the selected image. The branch point can define a branch from the selected image to a second linear arrangement of images. Additional images captured during the interactive session are received. The second linear arrangement of images is generated that includes the additional images.
