Forum:Unused profile images

Every time we go through a "change profile" picture movement. We usually end up uploading a ton of pictures, most of which do not make it past the talk pages. Do we have a "retirement" date for those pictures? I mean, can we at some point take them off the talk page and delete them or is it cool for them to sit on the talk page and the image database indefinitely?
