The present invention concerns a method and device for transmitting images of a sequence of digital images between a server device and a client device connected by a communication network, the images being coded in a format allowing access to spatial sub-parts. The method comprises a prior step of receiving a follow request specifying a spatial area of an image in the sequence previously received by the client device, and steps of: determining the following image in the sequence of images to be sent to the client device determining a spatial area in the following image to be sent, corresponding to the specified area, according to the estimated movement in the sequence of images, and sending to the client device at least some of the image data of the area thus determined. The invention also concerns a method and device for receiving images transmitted according to this transmission method.
