Fix my Lovable app — please make these exact changes in the Lovable editor:

Add alt text to all images

1. Add descriptive alt text to every <img> tag.
2. For decorative images use alt="" (empty string).

Why this matters

Most sites have 50-500 images scattered across components, blog posts, and product pages. Fixing alt one at a time is a week of work. Bulk-prompting an AI cuts it to an hour of review.

WCAG 2.1 level A compliance requires alt text on all informative images. This is a legal requirement in many jurisdictions (EAA, ADA).

Frequently asked questions

Can AI write good alt text?expand_more

How long should alt be?expand_more

Under 125 characters. Describe meaning, not pixels.
