Here I have used the Clone tool to make the bottom of the mirror on the slanted side, where the lasso didn't pick up the bottom of the mirror and the wallpaper is still there, I can use one part of the mirror to look like the opposite so that no one knows it was suppose to be like that.
Here I have copied the cropped picture mirror into the new Background taken from here (http://www.unsigneddesign.com/zenpaper/IMG_2008.JPG) and some areas need Erasing as they look unreal and not straight. By doing so you click on Layer 1 in the Right hand panel and click on the Eraser tool and by holding down and moving the mouse you can erase the areas you don't need.
In this section I have edited the lights by going to Filter - Render - Lighting Effects. I found this was different to that in Photo Impact 10 but the Cloning and the Eraser tools are similar.
