When this tool is useful
Review image descriptions in a page fragment before publishing an article or a product template. The report lists each image source, alternative text and loading metadata, separating missing attributes from deliberately empty values. This helps a content editor find markup that deserves attention without fetching the images or running scripts from the page.
Reading the result and limitations
An empty alt attribute can be correct for a decorative image, while a meaningful image generally needs useful equivalent text. The tool flags cases for review and cannot decide whether a description communicates the right meaning. It inspects img elements only, not CSS background images, rendered visibility or the complete accessibility tree. Pasted HTML stays inert in the browser, and external image sources are not requested.
Example input
<img src="product.jpg" alt="Blue ceramic cup"><img src="decoration.svg" alt=""><img src="banner.jpg">
