Hi Szoke,
Greetings from Syncfusion support.
Based on the details you shared, we have prepared and
validated the mentioned issue in the Blazor FileManager using Syncfusion
Blazor Template Studio. However, we were unable to replicate the reported
issue, and the uploaded image file displays correctly in preview format on our
end. For your reference, we have included the FileManager sample with the
latest version (20.1.38).

Check out the shared sample at your end. If you are still facing an issue,
replicate it in our shared sample or share the steps to replicate the issue with package version(if possible provide issue video
footage). It will help us validate and provide a prompt solution.

Leo Lavanya Dhanaraj
