Alt Text, Image Captions and Accessibility | February 9, 2005
Here’s an accessibility question for everybody out there. If an image has a caption that accurately describes the content of the image, do you still need to add alternative text, or would a blank alt attribute be OK? Whereas some screenreaders can read link text out of context, I don’t believe there are any that read images out of context. As such, apart from when images are links, I can’t see a situation where the additional duplication of the image caption in the alt text would be useful. However I can see that for large photo gallery style pages, the duplication could get very irritating to screenreader users.
What do you think?
