People may have remarked that there are a number of photos that have disappeared from the forum. Apparently, this is due to the fact that they are hosted for free and the site (image shack) doesn't keep photos if they aren't looked at regularly. I will try put back the photos that have disappeared (those that I put on) and look at the photos more regularly, so that new ones don't disappear in the future. If anyone has another solution to the problem, please let us know.
