Inserting Images
Setting a Border
To add a border around a picture, enter the border's thickness in pixels in the Border Thickness field on the Picture Properties dialog box.
Here is a picture with a 1 pixel border.
Here is the same picture with a 10 pixel border.
If the picture is not a hyperlink, its border is black. If the picture is also a hyperlink, the border is the same color as a hyperlink (for example, blue or purple if visited).
