I’d comment on how right-click disabling isn’t going to stop anyone blessed with something called “a brain” who wants to steal your work and your bandwidth, but I think that’s been covered.
I notice there is no link or any easy way to get to your other server, so I have no idea what type of server it is. Have you thought of putting in measures such as such as are discussed here for Apache?
Or, as was suggested in here earlier, just create a website with dynamic pages - use php to create the pages dynamically (like is done with the vBulletin software we are using right now), and they’ll have a bit more trouble getting to them to link.
But once they see the art, it’s theirs. One way or another they will get it.
I notice that you also mention the following:
The comment “I don’t mind if they look” sets off some alarm bells in my mind - this implies, along with the fact that there is no link to your other site from the one in your profile, that you are in fact trying to hide the site. So why not just hide it? Just make it password protected or a secure server and be done with it?
Another thing might be copyright and/or legal notice. Since I can’t find your other site, I have no way of knowing if you have a large link on every page labeled “Using these Photos”, which goes to a page which explains in detail your policy. You know, the way human nature is, a lot of people just assume if you don’t have a notice like that, they are free for use - even if you put the little “Copyright by…” at the bottom of every page. You are going to need a legal terms of use document, especially since your statement here that you allow limited re-creation of the art/photos weakens your legal position unless you have written it down.
This also bothers me:
Well, I have no idea whether or not copyright was “unknown” to Mozart, but the Statute of Anne, which passed into law on 10th April 1710, did introduce the concepts of an author being the owner of copyright, and of a fixed term of protection for published works. Mozart was born 46 years after this, so at least in some countries, copyright was in fact a known concept during his time.
