It's always a great idea to have a backup copy of your games original images as well as your ave game files. Also, if you name your images anything other than the original names and put them in your games image folder they will not display in your game. You will only see large blank boxes (usually blue).

Any image added to the game folder while the game is open will not be shown until after closing and reopening the game. If you still can't see your new images (kids room) then hopefully someone can help figure out what the problem is. Are you playing on a Mac or PC computer. What operating system are you running? Answers to these questions could help others to assist in trying to figure out the problem.
