Through a semio-pragmatic approach, this thesis proposes to analyze the multi-media circulation and the repetition of images in the media sphere. Our case study takes as an example the images of the Star Academy 4 broadcast which are transferred in the magazines and on Internet. The images are the subjects of institutional, personal and community re-using widely visible on blogs, chat rooms and personal websites on Internet. The first part of this work concerns the structuring of the broadcast's images transfers and the effects of these transfers on the readings; the second part takes an interest in the uses of the transferred images. The analysis reveals a great number of body images reusing carrier of emotion, which generates teenagers identification and projection processes. The images appropriation by "technophilic" users are both physical and symbolic and refers to the control of image as an object widely invested emotionally. The uses also reveal graphic contaminations, from one medium to another, which generates a necessary continuous adaptation of the readers' visual repertoires. The images re-usings visible on-line are mostly assembled within community sharing structures and lead to "Fan Art" creations which show a modelling of the practices and the uses of images.
