A Base64-encoded image string or a URL to the image.
Change effective from 2025-10-27:
The image property now contains a complete image source string instead of raw Base64 data.
Depending on tenant configuration:
- Tenants with Business Central natively hosted image storage receive a Base64-encoded Data URI, e.g.
data:image/jpeg;base64,<encoded data>
- Tenants with hosted image storage receive an HTTPS URL, e.g.
https://image-service.example.com/<imagename>.jpg. The URL is time-limited and secured.
Both formats can be used directly in an <img src> attribute.
Clients that previously decoded the Base64 manually should update accordingly.
