I believe thats not a really good idea, there are many ways to rip images and just by blocking the most obvious one wont stop the problem.
I agree, it gets annoying when I try to copy an image I posted before, and people can always use Ctrl+PrtScrn to copy the images anyway.
Thanks for giving out a shortcut I never knew.
I would have said ctrl+c, select it and go to edit and to copy, print screen, put your mouse over it and a thing comes up letting you save it, and the list goes on a while.....
Its really annoying when I want to get the URL of my avatar or sig.. I have to go to my control panel <_<
