I've done a bit of tidying-up and re-arranging in the Gallery, mostly concerned with the Society Events (http://gallery.orpington-astronomy.org.uk/index-6.html) section. Within that, the link-words have also changed, so I've also done some tidying-up of the link-word directory (which had managed to acquire not-so-useful additions like "the" and "at"...).
Generally, if you want to make images easier to find, give them a clear distinct title. Then the Search can be used to find them most easily.
