I've been busy on the blog over the last few weeks. I'd noticed that most of the photos older than a year had disappeared. This is because I've moved servers a few times and the free web space I was hosting old photos on went down for good.
The photos are all now on Picasa's servers, and I'm assuming Google's storage is as reliable as you're going to get so, unless they change their links, I should be sorted now.
As I was doing the painstaking work of relinking photos I knew that no one would even notice the results (unless they clicked the Go To A Random Post link), but this is mainly for Anne and me (I especially use this blog as an alternative to having a memory).
