Hello @rlaks5757,
Thank you for posting on our forum.
Some images found in DOCX files are not supported in the default configuration of WebViewer. See this forum post for more information, including suggested workarounds: https://community.apryse.com/t/some-images-charts-appear-as-gray-rectangles-in-webviewer/4504
With cases such as the one in the forum post linked, it is expected that converting the file to PDF with our SDK would successfully convert the image as well, despite it not showing when loading the original file.
Let us know if any of the above solutions work for you!
Best Regards,
Jacob Romano Carlsen
