Thread:Project:Support desk/Wanted page from image with no reference to that page

Our wiki reports a number of "Wanted Pages". Clicking the "# Links" link to view the "What Links Here" page for the wanted page shows several images. However, nothing in those images references that page. In some cases, the image has been deleted, but in other cases the image exists.

It looks like the image was used on the page, then the page was deleted. Why does the image still reference the deleted page? Is there a workaround to this issue? A large number of deleted pages appear on our list of "Wanted pages" making the report useless.
