Hi Maciej Because of the different support provided by AT the safest bet would be, if the image is the sole content of a link, a description of the links target page, not a description of the image. for example: <img alt="Sgt.Pepper and Robinone Individual Photo Page"> This way if the image/link combination is accessed out of the context of the implicitly associated title text (e.g. if the user tabs through the links or uses the G key - in JAWS to navigate through images or uses the JAWS link list functionality) the user will be provided with useful information about the link target. I think the main point is, that the omission of the alt attribute in any of the examples provided is not the answer.
