The information at https://www.ebid.net/uk/help/selling-on-ebid#faq-13 that stated unused images in a user's My Gallery area will be deleted after 10 days would appear to be out of date. The My Gallery page now states it is 365 days and user experience would indicate that that is the case.
Maybe have a sign made up to go over the programmers' desks reading "DON'T FORGET THE HELP FILES"?
