AFAIR according to JIRA, it might be an DNN internal bug, which should be fixed in a future Version.

Add to your appsettings in the web.config:

<add key="DnnImageHandler" value="EnableServerCache=false;" />

Added to the web.config and error is gone.

Would I need to remove it in the future should the bug be fixed?
