I'm thinking about ways to discover this, like for instance a personalized url that one (the admin/siteop) could trace back to the person having linked outside of the forum to begin with.

* For instance:

www.myforum.com/showthread.php?t=13 is normal
www.myforum.com/1ac5bfre44g55wd34.php?t=13 would, for example, be an url generated specifically for my account.

If I find this link somewhere where it shouldn't be, or an IP from outside the excisting userbase would use this link, I'd know where it comes from. Is this possible?

* Additionally, professional photo's will be posted on this forum, leaks isn't what I'm going to be happy with (the same will go for my userbase) out of commercial interests. I haven't been able to find a plugin that could do this. In essence a plugin that "stamps" the picture with hidden info.

My userbase won't excist out of IT-tech's so a little bit of security based on naivit? will suffice

English isn't my native language, I hope you will get what I am trying to say.
