I consider Wikimedia to be a lot more stable than most sites at the whims of their operators. Many are savvy enough not to arbitrarily rename or delete web pages (so they don't adversely affect their google ranking) but images are often replaced or deleted. Yesterday I wanted to point somebody to an image of an old AA sign that had some historical significance (it is also part of the story in identifying Cilrhiwiau as the pre-WWII name of Capel Dewi) but the site operator had inexplicably removed it. My county council are not only stupid enough to delete images, they completely deleted a whole set of historical web pages in preparation for a multi-year process of re-cataloguing the data. Can anyone say "301 redirect"? Not at Ceredigion County Council. Can anyone say "Keep each existing page until its replacement is available"? I think you can guess the answer. So my preference is for Wikimedia, which doesn't arbitrarily remove images because they get bored with them, or marketing decides to replace them, or the site operator goes bankrupt, or... These days I also trust Geograph for stable (ish) images. Either or both of those could go bust, but I think there are too many interests dependent on the Wikimedia Foundation for that to happen. -- Paul
