Will It Vibe?Image without an alt attribute
Part of Documentation, UX & Accessibility, which counts for 15% of the overall score. When this check fires it deducts 8 points from that category, once per scan, no matter how many places it turns up.
What it detects
An <img> with no alt attribute gives screen-reader users nothing to announce and fails WCAG 1.1.1. Svelte warns on this. Provide descriptive alt text, or alt="" for a purely decorative image so it is skipped.
Why it matters
An <img> with no alt attribute gives assistive technology nothing to announce, so screen-reader users get no idea what the image conveys, and the page fails WCAG 1.1.1. Svelte surfaces this as a build warning. Missing alt text is one of the most common and most visible accessibility defects.
How to fix it
Add descriptive alt text that states what the image communicates, for example alt="Quarterly revenue chart". For an image that is purely decorative and adds no information, use an empty alt="" so screen readers skip it. Do not restate the word image or photo in the text, and do not leave alt off entirely.
