                 Modifying an Image

                 When you insert a new image, you may need to modify it to suit the document. Modifying an image means to make
                 changes in an image like crop, resize, add border, etc. Here we will discuss the use of the Image toolbar for resizing,
                 cropping, and a workaround to rotate a picture.

                 Using the Image Toolbar
                 As soon as an image is inserted or selected in a document then the Image toolbar automatically appears on the screen.
                 If in case it is not visible, then go to View menu and select the Toolbars → Image option. Using the Image toolbar, you
                 can edit the image in different ways.
