Does anyone have experience using long descriptions for complex images embedded in Canvas? I've already tried editing the html to add the longdesc attribute to an image, but after I save the page, the longdesc attribute is removed. Is longdesc not supported?
Basically, I've got a bunch of diagrams which are embedded in quiz questions. The descriptions of the diagrams are much too long to use alt text.
Using longdesc would be the best option, but if it won't work, maybe I have to actually create a visible link below each image that links out to an accessible text version?
Any suggestions? Thanks!
