Hi sorry I'm still really new as you can see from the registration date and sorry if this doesn't belong but... I've seen in the mod forums like download this because halloween is near and they made like a new room look- but does it look like that in the game if I download it or is it just a picture to gaze at? Thanks!

You can find a list of steps to install image modifications (mods) here. Just so you know, however, if you bought your game from somewhere other than LDW, you may not be able to do this, because some game sites package the game in such a way that you can't access the images.
