Image alt text badge von lucerowb

Browser extension that overlays each visible <img> with its alt text so you can audit image accessibility at a glance. Missing or empty alt values show a clear warning badge. The overlay tracks layout changes, so it stays useful on carousels, modals, lazy-loaded images, and single-page apps.

Features

• Toggle badges on or off per session from the toolbar popup; the choice is remembered with chrome.storage.local.
• Live counts: total images, images with alt, and images missing alt, plus a simple coverage bar when badges are on.
• Content script runs at document_idle on all URLs; the popup can programmatically inject the script on the active tab if the page loaded before the extension was ready.
