Cover for ISO file via Metadata

Hi.Just a few covers cannot (I can’t do it) add through metadata Origin. Most of them are ISO…and Audirvana Origin can read perfectly those files, but I’m not able to add any pictures on them.Thanks who helps.

ISO file format is difficult or impossible to add Metadata. Best is to extract them to flacs (or dsf). Those formats are capable to edit Metadata.

Thanks mate!
