Process Images(s) Option Missing

Hey all,I'm a bit new at this, but I've been trying to install my own version of the script, and (after working out a few bugs), I got to the point where I was supposed to hit this option called: "Process Images(s)" in the Pixel Admin menu. My problem is that the whole thing is missing! I'm pretty sure that its really just a case of my looking in the wrong place, but I'd like some help in trying to track-down what's gone wrong. Please, advise!
