I have the DLC version of the game. The two zip together replace a total of 8 files. I grabed a full save and checked, before I do a playthrough and everything is censored.It depends if you're running a Mac or a windows.
If on Mac: you right click on the app and show package contents: then navigate to contents/resources/app.nw/img/pictures and put them in there replacing the relevant files.
If on windows you go into www/img/pictures and put them in there to replace the relevant files.
