Setting Tracing Image Page Properties options
The Tracing Image category lets you insert an image file for use as a guide in designing your page:
Tracing Image specifies an image to use as a guide for copying a design. This image is for reference only, and does not appear when the document is displayed in a browser.
Transparency determines the opacity of the tracing image, from completely transparent to completely opaque.
