How to delete files from the File Upload Manager

[wet_ride]

If you hover over the thumbnail a little box will appear. Tick it and delete it.

It will not vanish immediately, it is done as a cron job by the server.

Maybe for an administrator.....

This does not work... There is no little box.... when hovering in attachment manager only thing that appears is a question mark...

the question mark tells me what thread the picture is posted in.... if I go to that post, I can't edit the post to remove the picture to allow the chron job to remove unused picture. I assure you the above does not work.
