# Credential Image Upload Instructions

## Generated PNG Files

PNG files have been generated from SVG sources for Entra VerifiedID compatibility.

## Upload to CDN/Storage

1. Upload all PNG files to your CDN or static storage
2. Ensure files are publicly accessible via HTTPS
3. Update manifest templates with the image URLs

## Recommended URLs

- Default: `https://cdn.theorder.org/images/credential-logo.png`
- Diplomatic: `https://cdn.theorder.org/images/diplomatic-logo.png`
- Judicial: `https://cdn.theorder.org/images/judicial-logo.png`
- Financial: `https://cdn.theorder.org/images/financial-logo.png`

## Update Configuration

After uploading, update:
- Manifest templates in `manifests/entra/`
- Environment variable: `ENTRA_CREDENTIAL_LOGO_URI`
- Or in code: `logoUri` in `EntraVerifiedIDClient` config
