Extension test page

Three of these four images carry real AI-generation markers in their file bytes (Midjourney, Stable Diffusion, and a Content Credentials AI stamp). The fourth is the same photograph as the first, with a clean file and no marker. With the ImposterShield extension installed, the toolbar light should go red with a count of 3, the three marked images should get outlines, and the clean one should be left alone.
