We are evaluating how to best create thumbnails as well as how to manage images accessible by web readers. When web content is loaded and a web reader “reads” the content, the images are translated and read to the user. If the image has some content, it will try to read it, except if it is tagged accordingly using, for example, alt attributes.
When loading any gallery , or adding images to hub sites, I did not see a way to tag the thumbnails when loaded or configured the galleries accordingly. I am looking for any suggestions on how to make the galleries, hub sites, or other content more accessible to web readers. Thank you.
