Image bookmarklet will mark all images on the web page along with alt text and provide accessibility testers with a easy method to identify informative, decorative and images of text.

Images Bookmarklet for Accessibility Testing

Images Bookmarklet for Accessibility Testing inserts a green dashed outline around images that have alt values and a red solid outline around images with no alt attribute. Alt attribute values are displayed in black on yellow text on top of the images. Images with empty alt values, are shown as alt=””.
