Juicy Studio's Image Analyser scans every image on a webpage and checks accessibility attributes: width, height, alt text, and longdesc.
It automates a check that's tedious to do by hand across a page with many images, flagging exactly which images are missing alt text or other required attributes instead of requiring a manual pass through the page source.
Developers doing an accessibility audit on an existing live page who need to quickly find every image missing proper alt text.
Run it against the live URL rather than local dev files, since it needs to fetch the actual rendered page to check image attributes.
