Daily Accessibility ReviewImages Missing alt Attributes in Carousel, Istio Page, and ReceiverIcons

[github-actions[bot]]

Summary

Several <img> elements across the codebase are missing alt attributes. Images without alt attributes are inaccessible to screen reader users and fail a Level A WCAG requirement.

WCAG 2.2 Reference

• SC 1.1.1 – Non-text Content (Level A): All non-text content that is presented to the user must have a text alternative that serves the equivalent purpose. Images must have an alt attribute. Decorative images should use alt="" to be hidden from assistive technologies; informative images must have descriptive alt text.

Affected Files

1. shell/components/Carousel.vue (line 198)

Slide icon images have no alt attribute:

<img :src="slide.icon ? slide.icon : `/_nuxt/shell/assets/images/generic-catalog.svg`">

These images visually represent application/chart icons in the app catalog carousel and should have descriptive alt text (e.g., the chart name).

2. shell/pages/c/_cluster/istio/index.vue (lines 101, 137)

The Kiali and Jaeger logo images have no alt attribute:

<img :src="kialiLogo">
...
<img :src="jaegerLogo">

These logos are informative (they identify the service) and should have alt text like "Kiali logo" and "Jaeger logo".

3. shell/components/formatter/ReceiverIcons.vue (line 98)

Alert receiver type icons have no alt attribute:

<img :src="type.logo">

These icons visually distinguish receiver types and should have descriptive alt text derived from type.label or similar.

Recommended Fix

For informative images, add descriptive alt text:

<!-- Carousel slide icon -->
<img :src="slide.icon || fallbackIcon" :alt="slide.chartNameDisplay">

<!-- Istio logos -->
<img :src="kialiLogo" alt="Kiali logo">
<img :src="jaegerLogo" alt="Jaeger logo">

<!-- Receiver icon -->
<img :src="type.logo" :alt="type.label">

For decorative images (images that add no information beyond what surrounding text already conveys), use alt="".
