William, If you look at the words used in menus, you will find a similar problem. Certain commands seem to always appear under file, edit and view, but other commands are found under insert in one program and under tools in another. There is also an inconsistency problem in choosing to use a command from an icon over using the same menu command (e.g. in many programs, clicking on the save icon doesn't allow renaming or saving to a different location, which can only be done with the menu commands. Likewise, those who use key commands have to learn a new one with every program. What is lacking is a set of standards for presenting menu options, icons and key commands that is used in all programs. Some seem to be developing, such as "file", "save", "open", but they must all be learned. Words are really not any more precise. Simple words can be encompass a wide range of meaning. The word "dog", for example, indicates the species of animal, but not the breed, size, color, coat, or age. All these specifics require additional words, phrases, sentences and/or paragraphs. All of these specifics can be included in the same graphical presentation. Isn't the saying "one picture is worth a thousand words"? If for some reason you wanted to know what I look like, it would take a great many words, some of them quite equivocable, but I can easily and less equivocably accomplish the same goal by sending a picture of myself. Incidently, some part of the movement away from McGuffy readers was the additional requirement that schools reach/teach all children, not just those who "take to" text. Current educational philosophies and practices require that content/skills to be learned be presented in a range of input styles, especially, visual (both graphic and textual), auditory, and tactile/kinesthetic. It is perhaps the same route that must be taken to accomodate the cognitively disabled (some of whom were historically turned away from schools) on the web. >So after such a long rant I guess I still don't see any proposal for a >reasonably *objective* guideline to make any of this easily doable.

William, I started using "meaningful graphic" and it didn't seem to work for everyone, then started using "illustration" in hopes it would convey a more easily interpreted meaning. I'm open to suggestions for another way to put this into words so that it can become an effective guideline. If all graphics used as illustrations aren't perfectly wonderful, it will be no different than the original requirement to include an alt tag that had to be re-defined to specify that the alt tag should be more than naming the graphic and more than a blank, but doesn't specify what exactly has to be stated in the tag. It's a judgement call what words to use, whether to use a single word, a phrase or sentence, or if a longer description must be included. So, it will also be a judgement call whether to include an icon, a drawing/art work, or a photo. It will be a judgement call whether to include a generic dog, or a specific dog in the graphic. But the guideline should make it difficult to justify a picture of a cat on an otherwise un-illustrated dog-not-cat page/site. Anne Anne L.
