So I don't want to steal mike time from anyone. But this image is a classic, and there are some little-known but worth knowing things to say, here. ** executive summary ** This image is much more substantive that "purely decorative." It is an artfully composed and methodically themed image. On the other hand, it is _inessential to any banking or page function_. The motivated visitor doesn't need it. It motivates the visual user. It evokes a marketing theme. A theme blind and visually impaired people care about a lot. If text you put in as ALT is de-motivating, it's not a functional equivalent and just lose it. But then you have to think as to how to work the messaging that this image bears in the GUI presentation into the audio flow for the screen reader user. If you can. You are not really ready to ask screen readers what they like. Just laying the "purely decorative" epithet on this image doesn't give your respondents nearly enough of an idea what this image is doing on the page to give you informed feedback. I've tried to remedy that a little, here, But you should prepare and expose concrete alternatives that present different ALT strategies in page context. The flow through the ALT is critical. Lots of the people receiving your mail have been around enough to be able to answer a question as abstract and theoretical as the one you posed. But this is bad "experiment design." To get results that are more reflective of the person in the street and how they will vote with their feet, offer a range of mockups. You will learn not only from the spread of preferences, but from specific comments about each mockup. You will learn much more and can extrapolate with more confidence from what you learn. ** discussion/explanation * this picture tells a story that delivers a message * The image I mean is the one at <<http://www.bankofamerica.com/images/banners/ban_acc_01.jpg>http://www.ban kofamerica.com/images/banners/ban_acc_01.jpg><http://www.bank/>http://www.bank ofamerica.com/images/banners/ban_acc_01.jpg It is an image of someone sitting with a laptop open in their lap. Nothing is around -- maybe they are on the beach? Oh, yes -- they're in a wheelchair. The picture tells a story. It is a positive story, and it is a story about BankOfAmerica's online offerings and access to banking services. It doesn't take a rocket scientist to draw a plot thread between this picture and "Accessible Banking." If you're in Starbucks with a WaveLan card, heck, you can bank from wherever you park your chair and sit. No muss, no fuss. Or wherever you are, and whoever you are, we make banking available online so your accounts with BankOfAmerica are much more accessible than branch banking alone would accomplish. That last statement of the plot puts it in the main current of a message that resonates strongly with your blind and visually impaired customers. Put on your advertising agency creative department hat; shift gears: if this service is on a voice portal over the phone, how do we represent this positive quality of the services the bank offers? It is a tag line that speaks when you first hit the site, on the order of the credits on National Public Radio that they give for sponsors. This one sounds something like "Bank of America, ready when and where you are." And then it gets right down to business. The image on this web page adds the "ready when and where you are" theme to the page. Now, it's no accident that you notice the laptop in the picture before you notice the wheelchair. This person is depicted as a mobile professional first, and a person with a disability second, and don't think the art department wasn't instructed that it wasn't to be any other way. So this image represents a lot of thought and verbalization. But still, the function of the image is to motivate people to feel good about their bank because online availability of service makes it very near to hand, and handy to use. If one can't flow something into the auditory experience that goes down easy and leaves a positive taste, well, heck. forget it. Just the facts and let me do my banking, thanks. Note: the 'anywhere' theme is a constructive and I bet conscious part of the imagery. The vagueness and emptiness of the setting the person in the chair is found in conspire to send this message. There is nothing of note in the picture arond the wheelchair. This emptiness evokes the current cliche of the laptop in your beach chair, and the message that anywhere you have a computer, you can access your bank accounts from there. With a little standard advertising hyperbole in imaging the 'anywhere.' So the team has some theming work to do. Integrate the team that is picking pictures to sell banking services with the team coining the text phrases for the ALT text. The role of these pictures could be described as "mood photo" or even FeelGood photo. But let's save the 'FeelGood' language for inside the creative team and for the public ALT of this particular image-slot in your page design, let's stick to 'mood,' because that indicates both how there is an "accessible-banking message" that is imparted by this image, but also that it is not essential to the conduct of business with the bank. Despite BankOfAmerica being a California Bank, customers don't have to "share the experience" to be allowed to do business with them. So a possible ALT for this image would be "Mood photo: reachable by computer, anywhere, any time." A descriptive alternative could be "Mood photo: man sitting in wheelchair in open space with laptop computer open in lap." You can tell already that I don't like the second approach. In the development of the WAI guidelines we got a range of preferences from consumers using screen readers as to how much they wanted just the functional essentials and how curious they were about the visual contents of the page. You may find the same. But I think that you should take a business-positive approach, rather than a disability-defensive approach. Design a voice portal mockup for banking services. Craft a slot in there for a tag line which will accept a revolving slogan, just as the web page has a slot accepting a revolving sample from a collection of motivational images. SuccessWare for Banking. Then, for each image added to the rotation, boil its message down to a radio-ready tag line complying with the brevity guidelines for the voice portal slot. Then place and or frame this slogan in the audio flow through the web page so as to help it go by easily and comfortably. When I say 'frame' I mean things like the "mood photo:" prefix that explains a digression from the main flow of the page. But see what you can do to craft a smooth flow that just goes by easy. Note: The summary META tag talks access for the blind and visually impaired. If the pictures are purely decoration, and the site is an alternative site for the blind and visually impaired, don't waste the bucks to change them frequently. Or the bauds to deliver them. But that's not the case. This is a dual use design that should look and feel comfortable for lots of users. So fixing the META is on the worklist for the theming and messaging team. No ghettos, no handouts. Just put people first. Although the images change fairly frequently, the pixels aren't free and each image has made it onto the page because it has a story it tells that is part of the overall messaging program for the service delivered here. Once the picture picking team had had the experience of coining theme phrases for three pictures _that they actually picked_, they will be off and running. Getting new ALT will not be a big deal. It will be how the person nominating the picture explains the picture choice to his or her boss, organically to the picture pickin' workflow. Just spell it out, write it down. You're done.
