Really nice pics. I feel they all have a slightly blue cast, though. Is it your camera settings?
At 1024 px wide they are a tad too large for internet presentation. As a rule of thumb it is a maximum of 800 px wide that works best and even on the oldest monitors, so people who still have to use those need not scroll to see the whole photo.
All my family know that fish and have been there and read the inscriptions and taken detailed photos of the inscriptions (I know my sister has, but she is in the plane right now, on her way to Myanmar for three weeks) ... but I have never been where there is that fish. One MORE reason to go back to Ireland!!! (There are soooo many reasons!)
