Basically, disabling right clicking doesn't do much as there are other ways to copy photos. I've heard before that depending on the blog you use there really is no way to stop it. I always suggest just watermarking your photos, but a determined photo thief will not be deterred by that. The likelyhood of that happening with personal photos, though? Slim.
It's easy to by pass the right click feature but probably 50% of people don't know how so it's helping anyway. I use freewebs and it's got an option there "Disable right-click" maybe it's in options if it's with a blogging site but if it's your own website I have no idea. LOL!
IMO if you don't want your pics stolen, the only way is not to post them. If someone doesn't know how to bypass the no right clicking feature, I'm sure they would not even want to steal photos, because if they can't do that then they can't do much with the pics.
