Image ALT - A11y Image check
Image ALT is a simple Chrome extension designed to perform basic accessibility testing for images. It is a free add-on developed by Laurence Lewis in the category of Browsers, specifically under the subcategory of Add-ons & Tools. The main purpose of this extension is to check all image and SVG elements on a webpage to ensure they are accessible.
The extension provides several checks for images. It identifies all images inserted in the webpage using either inline styles or CSS, generating a message about the method of image insertion. It also finds image elements in the document and checks if they have an ALT text present, displaying the ALT text if found. Image ALT further identifies decorative images on the webpage based on attributes like aria-hidden and alt, with each classification accompanied by a message explaining why the image is classified as decorative. Additionally, it identifies images that are missing an ALT attribute and generates a message indicating the absence.
For SVG elements, Image ALT checks for the presence of accessible names. It categorizes SVGs based on certain criteria and generates messages for each case, explaining the status of the SVG. It also identifies decorative SVGs marked with 'aria-hidden true' and generates a message if an SVG is marked as decorative but has an accessible name.
