I was able to get a dock theme entered into the editor, but still cannot get it to apply. I used the "BezelStyle" theme from leoparddocks.com. I clicked on "New Theme" in PimpMyDock, then saved the theme to my desktop. I dragged each image into the image window on the editor. But when I clicked apply, there was no change--the dock remained default in both 3D and 2D.
No go on this dock-changing app, or any other, for that matter!
