Resizing pictures
You can scale pictures to make them larger or smaller using the Picture Content tool , the Item menu (Item > Modify), the Style menu, or the Measurements palette. After importing a picture into a box, you can choose Fit Box to Picture and Scale Picture to Box from the context menu (or Style menu).
