Examples I can think of that have been mentioned so far include: * Images uploaded by a blind user before that user has had a chance to ask his friends to describe the images to him. * Images in a Web-based tool whose purpose it is to get authors to provide replacement text for those images. * Images uploaded automatically by a completely automated system, e.g. a Web cam, or Google's "street view" images. * Images uploaded "em masse" where the user does not have the resources to describe each one in turn. These are the cases we are talking about. I gave an example a few days ago of a professional photographer uploading 1000 images a week to his photo gallery site. If it takes him one minute per image to describe his photos, he would have to spend two days a week full-time just to describe his images. Given that photographers are paid by the photo, and not by the word, I am very skeptical that you'll ever get a professional photographer to do this. If a tool was to demand it of him, he would just use another tool instead. We don't want to make sites have to decide between conformance and market share. If we make them make that choice, conformance will lose every time, and far more than alternative text is likely to be lost in the battle. -- Ian Hickson U+1047E )\._.,--....,'``. fL http://ln.hixie.ch/ U+263A /, _.. \ _\ ;`._ ,.
