In this paper the effects of steganography in different image formats (BMP, GIF, JPEG and DWTcoded) are studied. With respect to these formats, we try to give an answer to the following questions: 'how many bits of noise (i.e. the textual secret message) can be injected without perceptually deteriorating the quality of the image?' and 'how and where to inject these bits in order to achieve the best tradeoff in terms of length of the textual message and preserved quality of the image?'
