Thank you Missaldith.
To make paintings you need simPE. It's so easy...
all you have to do is open simPE, go to tools/object creation/photo studio. A window should come up with all the paintings from the game. There will also be a button that you can click to load an image from your computer and you just have to look through the paintings to see which one best suits the picture you want in your game. You have to make sure to uncheck flip image at the bottom which I apparently forgot to do so it's reversed. I'm about to fix that actually...:laughing:
If you need more help there is a thread on
