Transparency

Using the formatting toolbar and Picture dialog
When an image is selected, you can customize some aspects of its appearance using
the tools available on the Formatting toolbar (shown in Figure 267) as well as in the
dialog that is shown by right-clicking on the image and selecting Picture. You can,
for example, create a border around the image, selecting style and color; or you can
(in the Borders page of the Picture dialog) add a shadow to the image.
