Re: longdesc or aria-describedby for infographic

For a description that long I would either make the image a link to the description, or provide a visible text link to the description. The description could be useful to more folks than just those who use screen readers. If you were to use aria-describedby the description would need to be included in the content of the page and would not allow people to use many of their reading commands to control how they navigate the content. If the description is visible to everyone (not positioned off screen) then aria-describedby would be redundant. I would place the description immediately after the image.

Subject: [WebAIM] longdesc or aria-describedby for infographic

Hello,
I have an infographic and have been provided a description for it that is 2313 characters long. I'm wondering whether to use <img longdesc="description...." /> or use aria-describedby and position it off page.

Can anyone advise me as to what is the most preferred by users of screen readers?

Thank you
