There's another thing here guys that maybe I'm just missing but... flickr has this option of having your images be protected under the creative commons (CC) - the two people who have their images stolen I do not see any creative commons assignments on them - which could lead into someone thinking that they can steal them and use them - one advise is that regardless of the protections under SL... make sure that your images are protected visibly by the CC - that at least gives you some additional non SL ground to work on.
