Hmm, this is not a broken container image but a missing logo.

An image is needed, must have an open-source license, format preferably png that will have the path website/static/logo/virtualization.png, named after the subsection, after that the logo should be visible in the virtualization page.

For licenses, Fedora has a list of "good/bad" licenses which could be a good source should you be unsure if some image can be redistributed.

Please reach out if you have any further questions.
