Broken image icons look unprofessional and confuse users—graceful fallbacks maintain visual consistency and user trust when images fail to load.
Check if the website handles broken images gracefully with fallback images or error states.
Implement fallback images or placeholder content for broken image scenarios.
Explain how proper error handling for images improves user experience.
Review image assets, markup, and delivery configuration related to Handle image loading errors gracefully. Flag exact files or components where format choice, sizing, or loading behavior violates the rule, and describe how to confirm the fix in DevTools.
For full implementation details, code examples, and framework-specific guidance, see references/rule.md.

DecimalAI ran this skill against gemini-3.6-flash twice over the same eval suite — once with the skill loaded and once without — and compared the two runs case by case. 24 cases were attempted. The headline lift of +13 percentage points is the difference between those two pass rates over the 24 comparable cases.
Without the skill loaded, the model failed this case. With it loaded, the same prompt on the same model passed. This is one improved case from the latest verified run; every case, including any that regressed, is in the table above.
Other measured skills in the registry, with their headline benchmark lift.
