To create a new Image fill, go to Options > Element Attributes > Fill Types. Click New.
In the Add New Fill dialog box, choose Image fill.
In the appearing Fill Types dialog box, note (in the Availability and Screen only Pattern Panel) that Image fills can be defined as either Drafting or Cover fills (not as Cut fills).
For Image fills, the second panel is the Fill Texture Panel. Here, click the Load Image button to bring up a library directory dialog box. Browse for the desired image and click OK to load it.
Note that the “Mirroring” controls give you different options for setting up the repeating patterns within your Image fill.
