To display the ruler, go to the View menu and select Ruler. This will allow you to see if you have exceeded the half inch margin. If you need to adjust the size of an imported picture or logo, hold down the Shift button and click and drag on one of the corners in order to scale it proportionally. This will keep it from being distorted. Do not allow imported pictures to hang over the edge of the slide.
