If you're interested in what, in theory, should happen when one is cleaning out image CSDs, take a look at it now -- I edited the page to identify the copyright holder (we need to do this), added our standard fair use rationale for an album cover. I then orphaned the image, because it wasn't being used in the way the rationale specifies -- it was decorating a discography listing on the artists' page, not being used in an article about the album.
Shouldn't the image be deleted if it's orphaned? A fair use rationale is only for a particular use, as this image isn't being used, the rationale is nonsense.
