Alt Text Checker

This checker looks at the 'alt' attributes for each image on the page and displays the image (with 'alt' attribute) in its context on the page as plain text. The image will be highlighted within the context like this and the real image will be next to it. If the image has a 'longdesc' attribute this will be linked to after the image. All other text formatting on the 'alt' text and its context will be removed to simulate a possible speech rendering of the text.

Missing 'alt' attributes will be noted as an error.

This checker works best with valid HTML code and unpredictable results may occur with invalid code.

We are currently carrying out infrastructure maintenance, and as a result some website functionality is currently unavailable. We hope to have full service restored as soon as possible. We apologise for the inconvenience this causes.
