A method of capturing an image from a video call between a first user and a remote user over a communication network. The method includes receiving video data from the remote user at a client executed at a user terminal of the first user, the video data comprising a sequence of frames; the client capturing a frame of the video data responsive to a command from the first user; the client extracting image data from the frame; the client converting the image data to an image file and embedding a communication identity of the remote user in the image file, wherein the communication identity is suitable for initiating a communication event with the remote user; and storing the image file on a storage means of the user terminal.
