This is an archived snapshot of W3C's public bugzilla bug tracker, decommissioned in April 2019. Please see the home page for more details.
Here are some bugs filed against the ALT guidance document that also apply to HTML5 1) I think screen reader users should be explicitly informed that information below is the alternative... rather than deducing it from the heading above the alternative. alt="Flowchart: Dealing with a broken lamp."> I would add "full description below" alt="Flowchart: Dealing with a broken lamp. Full description below."> ======== alt="Bar chart: Average rainfall in millimetres by Country and Season." Same here alt="Bar chart: Average rainfall in millimetres by Country and Season. Table of data below." 2) I'm not sure of "more than a couple of sentences" being the guidance for providing a long text alternative. I've always understood it to be if it requires more than about 100 words, OR if there is a necessity to structure it, then a long and structured description should be provided. A couple of sentences means about 20 words. Do we really want people to start requiring a long description if the alt is more than 20 words? Remember, the general public will take this document as the final word... I would like other's thoughts on this. 3) Also I think we need an example of the long description immediately following the image, where it is hidden in an expandable tag such as the Details/Summary (or a JavaScript fallback) .... every developer I know resists long text following an image because they don't want to give up the page real estate.
On behalf of bug triage. Dave, can you seperate the three issues here into separate bugs? It'llmake them easier to triage and track. Thanks.

I think that this would be better handled by wrapping the img + table in a figure (+figcaption element) will do this. > > 2) I'm not sure of "more than a couple of sentences" being the guidance for > providing a long text alternative.

I believe all the changes related to this bug have now been backported to CR; anything missing?
Any further follow up on any of these issues I will take to 5.1 ... we can close out 5.0
