Make informative images understandable, accessible, layout-stable, and appropriately sized for their rendered use.
Informative images need concise alternatives, decorative images need an empty alt attribute, and rendered dimensions should reserve stable space.
Missing alternatives hide information from assistive technology. Missing dimensions and oversized assets can also create layout and performance problems.
One or more images provide no alternative-text decision at all.
Describe informative images and set an explicit empty alt on decorative images.
Inspect every flagged image and confirm its alt choice matches its purpose.
Several images are marked decorative, which may hide useful information.
Review whether any image communicates content, a destination, or a function.
Use the page without images and confirm no meaning is lost.
Some alt values are long enough to duplicate surrounding explanation.
State the image’s essential purpose concisely and move complex detail into visible text.
Read the alt alongside nearby text and remove repetition.
Rendered width or height evidence is missing for some images.
Provide intrinsic dimensions or a stable aspect ratio in the layout.
Reload under network throttling and confirm content does not jump as images appear.
