@Linux_Is_Best On the home page, it's a long list of posts, each with a thumbnail pulled from the source article. They add visual interest but are often misleading or irrelevant. The thumbnails' alt text could simply be a repeat of the post title, which would be repetitive and not add new information. For this reason I set every thumbnail's alt text to double quotes, hoping that screen readers would ignore the thumbnail entirely.
I'm not sure how to handle this, clearly. 😅
