How A11yied Tests This Criterion
A11yied automatically validates WCAG 1.1.1 using browser-based testing that analyzes your page in real-time.
Implementation: images.ts
Testing Notes:
Comprehensive coverage expanded: 7 rules now cover img alt text (with empty alt verification), input type=image, canvas, SVG, video captions, audio transcripts, and object/embed fallback. Total 1,182 passing tests. Icon fonts skipped (unreliable detection, modern usage is SVG). Empty alt text now flagged for manual verification - correct for decorative images but requires human judgment.
