I always think that the Internet is the ideal medium for people to share images. Whilst there are numerous sites where you can post your latest photos, there are few where you can share archive photographs. Where they do exist, such sites all too often are infested with the "I can make money out of this" virus and carry ridiculous copyright warnings. It is therefore refreshing to discover a site dedicated to the free sharing of archive photographs between people, like me, who see old photographs as windows to the past. The site is Photo-Ark.co.uk. It is well worth a visit and well worth an extended browse.
