Forum:Is there a way to request or do mass deletion of unused images?

Hello, I am getting around to sorting images on my wiki from previous uploaders but many of them I do not need as the site which they are from are contains many many images for one item, it is rather overwhelming, I found an easier solution to displaying images for articles. So, must this task be done manually or can a bot be requested, and if possible what would I need to do in order to complete this? -- Bunai82 (talk) 04:36, May 9, 2011 (UTC)
 * Pretty sure it would have to be done manually, but it could be sped up by making it something all admins work together on. --W H  (Talk) 05:18, May 9, 2011 (UTC)
