Images sourced via URL are not displayed when exporting a Stimulsoft report to PDF (CORS Policy)

Hi Stimulsoft team, We are using Stimulsoft reports and encountered an issue where images sourced via URL are not displayed when exporting a Stimulsoft report to PDF

Scenario:

* The report has an Image component using an external image URL
* The image appears correctly in the preview/designer
* When exporting/saving as PDF, the image is missing
* The browser console shows a CORS error:
"No 'Access-Control-Allow-Origin' header is present on the requested resource"

We understand this is caused by browser CORS restrictions and that cannot control the external server configuration.

Question:
If external image URLs are blocked by CORS during PDF export, what is the recommended way to include images in Stimulsoft reports and able to export?

Specifically:

* Can the image be uploaded directly into the report template instead of using a URL?
* Is it better to use images hosted from the same domain?
* Are there any recommended Stimulsoft approach to ensure images appear correctly in exported PDFs?

We want to confirm the most reliable approach before advising our client.

Thank you

Hello,

You can store images directly in the report resources, but this increases the size of the report template. The best option is to store them on the same domain.

Thank you.
