Re: CfC on good practices for images

Continuing the conversation on SVG titles vs desc use.

Titles provide tooltips.
Should the potential tooltip be a factor in deciding whether to use title
or desc?
Obscured objects won't show a tooltip even if they have a title. Should
that play a role in choosing title and desc?
What if the author does not want a tooltip on the object? Is using a desc
OK?
Would having an aria-labeledby influence whether you use a title or desc?

I hope we can create some simple guidelines that is easy for authors to
understand.

If you wait long enough with focus on the right place, it may go ahead and
read the description too, but I haven’t tested this yet.

Conceptually, the functions are different: DESC is supposed to be more
detailed, whereas TITLE is the short name that one would use for
navigational purposes or while exploring the content to obtain an overview.
In many cases, TITLE alone should be sufficient. To me, DESC implies that
you’re providing the details that a casual reader can safely ignore.
