It feels like I'm talking to the walls. Nmn...
There's no need to get rude.
You're asking the same question repeatedly and we're trying to answer, but it's honestly hard to understand what your issue still is after it's been explained a few times already?
Let me give it one more shot:
1) Not every scene has alternate content. If there is alternate content then when you have "Unlock" turned on, it will outline the scene in pink. If it is not outlined in pink, there is no alternate content available in the game. If it's outlined in pink, then when you click on scene it brings up the variable toggles to let you pick which version of the scene to replay - those big buttons to the right of the scene icon. Most of the toggles are just for the alternate outfits, but some are dependent on your game choices.
2) the picture you posted is "d7 library 11.jpg" and it is not in the game. Yes, the render is in the images folder, but it's not referenced anywhere in the code of the game. So again, if they don't have it included in the game code, then it's not going to show in the scene gallery regardless of if you use my mod or not.
