Display dynamic images correctly in Apsona merge documents, the image URL in your Salesforce field must follow these key requirements:
The full and final image URL must begin with http:// or https://.
For example: https://example.com/image.jpg
The URL must be a direct link to the image file itself (ending with .jpg, .jpeg, .png, .gif, etc.).
The URL must be publicly accessible or accessible to Salesforce users without requiring login or authentication.
Relative URLs cannot retrieve images from servers or cloud storage — only a complete, public URL will work.
If these requirements aren’t met, the image will not render in the generated document.
When you use a merge field containing such a valid URL in your document template, Apsona replaces it with the actual image at runtime.
