A method and system are provided for delivering video from a server to a client over a communication medium with a limited bandwidth. An initial image quality that allows the video to be displayed in real time at the client is determined based on a predetermined frame rate and the limited bandwidth. Video having the initial image quality is transmitted to the client. The client sends to the server a snapshot request that specifies both an image in the video and a destination. In response to the request, the server generates a digital representation of the image that has a higher quality than the initial image quality. The server transmits the snapshot to the specified destination. The specified destination may be a destination other than the client, such as an image processing facility, thereby allowing the client to log off without waiting for delivery of the snapshot.
