Thread:Project:Support desk/How to remove old comments from an image/file?

I uploaded an image to my v1.14 wiki, put some text in the comment there, changed that text afterwards, and now want to remove the record of that comment from view. I used Manual:RevisionDelete, which works to remove it from the history page. However, the original text on the image page itself is still visible in the file history table on the image page. How do I go about remove the original comment? Found a comment at Manual:FAQ - "Administrators can delete an old revision of a page by deleting the page, and then selectively undeleting revisions to be kept". So then I delete the file and recover it?
