I've used a somewhat different approach to displaying the examples in this article. The "What it looks like" and similar sections are set off in in a box with a white background. I find it much easier to look at than the table examples used on many of our example pages. Think it could be used in other places too? Granted, it makes the article quite a bit longer, but it's less prone to uglification with smaller screen sizes. I'm interested to know what you guys think of this. -- Wapcaplet 14:48 13 Jun 2003 (UTC)
alt
text by visual browsers (putting it in a box) is perhaps the single greatest reason why authors write accessibility-unfriendly alternate text in the first place. For that reason, the rendering you've imitated is (as I said earlier) regarded by the Mozilla developers as a bug in Mozilla; they plan to display alt
much the same way Lynx does, to encourage people to write alternate text properly.
alt
goes in a box" thinking by showing it in this article, that will undo any positive accessibility effect this article might have had. It's much less important to me that alternate text looks ok for people who have a choice about displaying images anyway, than that it works well for people who will never have such a choice. -- Mpt
P.S. - Also, I would tend to disagree with the "DIVs are the tofu of HTML" assessment. In my web design work, I've found DIV to be extraordinarily useful in giving a document structure and semantic organization. Yes, ideally, images should format themselves according to CSS class characteristics, but we don't always want images to float to the right, necessarily. DIV is great for things like placing a navigation bar, setting examples off from other text, making footnotes or sidenotes, etc. Can you recommend an alternative method of doing such structural organization without using DIVs? -- Wapcaplet 14:56 13 Jun 2003 (UTC)
ul
(which can be styled to run horizontally, if you want). Your examples in Wikipedia:Alternate text for images are quoting what an article might say, so use blockquote
. For your "etc" I'd have to see your source code.

code with the alternate text. And while Google Images does index using alt
, it does not replace images with their alternate text; if it did, nobody would use it. -- Mpt 18:08 13 Jun 2003 (UTC)
100 examples of images being used in Wikipedia, and good alternate text for them. -- Mpt 02:03 15 Jun 2003 (UTC)
Another good reason to use non-empty alt text is the fact that all images in Wikipedia articles are links (namely, to the image description page). Using an empty string (or even an empty space) for a hypertext link is not recommended by any web authority I know of.
Specifically, from Flavell's article:

I think that this is a rather important point.
In response to a question to me from Mpt that has now floated into archives, let me explain the perspective that I come at this from: a Wikipedia editor that sometimes browses Wikipedia with a text browser.
I want Wikipedia to be useful to blind users, but I also want Wikipedia to be useful to me.
And an empty ALT
tag is worse than useless when an editor browses with a text browser, because then we don't know what's going on in the page.
I've never seen any reason yet why "Photo of Karl Marx." is harmful for any user.
Worse than other possibilities, such as a description of how he looks -- yes.
Useless for certain users, such as blind readers -- yes.
But AFAICT, it's useful for me and harmless for others, until a future editor writes something better.

I've been looking for external references that agree with Mpt's POV, and I've managed to find one: [1] (http://www.cs.tut.fi/~jkorpela/html/alt#content) says "Redundant images call for empty alt". That is along the lines of Mpt's approach. Author: Jukka "Yucca" Korpela. It's an interesting page, and while it agrees with Mpt on this point it disagrees on others. Martin
I see some interesting Rules of thumb (http://www.cs.tut.fi/~jkorpela/html/alt#thumb) on that page, that somewhat agree with me but also (when looked at more closely) hint at ways to satisfy both me and Mbt. #8 notes the usefulness of
I'm going to remove the table containing the lettuce example, and convert it to DIVs also. The DIVs take up considerably more space, but here is what that table looks like in Lynx:
Don't do this Do this instead Wikipedia code [[Image:Lettuce.jpg|Photo of some lettuce]] A lettuce plant has a short stem initially, but when it blooms, the stem lengthens and branches. [[Image:Lettuce.jpg|Most lettuce varieties have a round mass of broad green leaves, with wrinkled edges.]] A lettuce plant has a short stem initially, but when it blooms, the stem lengthens and branches. What people hear "Photo of some lettuce A lettuce plant has a short stem initially, but when it blooms, the stem lengthens and branches." "Most lettuce varieties have a round mass of broad green leaves, with wrinkled edges. A lettuce plant has a short stem initially, but when it blooms."
Clearly not an accessible solution :-) Perhaps something similar should also be done for our other policy pages which make use of tables. -- Wapcaplet 15:37 17 Jun 2003 (UTC)
