Dynamic images in html report with Freemarker

Hi, I’m building a report that represents user image with fileDescriptor. In the documentation, it said something like this:


[link].

My code for displaying image was:

   <#assign image="fs://"+pr.photo.id>
                    <p style="display:flex; align-items:end;">
                        1.<img alt="candidate-image" src="${image}" 
                        style="padding-left: 10%;width:10vw">
                    </p>

But the image is not showing up;
