CI Artefacts
This check run embeds images generated by the CI pipeline directly in the output so reviewers don't need to navigate to external dashboards.

Image Field Reference
| Field | Type | Required | Notes |
|---|---|---|---|
alt |
string | ✅ | Shown if image fails to load |
image_url |
string | ✅ | Must be a publicly accessible URL |
caption |
string | ❌ | GFM Markdown; rendered below the image |
Constraints
- The URL must be publicly accessible — GitHub fetches it server-side and does not support authenticated URLs.
- SVGs are not rendered for security reasons. Use PNG, JPEG, GIF, or WebP.
- Animated GIFs work and are useful for visual regression diffs.
- There is no documented maximum number of images per check run.
Common use-cases
// After uploading an artifact to S3/GCS, include the public URL:
output: {
title: 'Test results',
summary: '87% coverage',
images: [
{
alt: 'Coverage report',
image_url: 'https://s3.example.com/ci/coverage-heatmap.png',
caption: 'Line coverage by file',
},
],
}
