You can use a tracing image as a guide to re-create a page design that was created in a graphics application such as Macromedia Freehand or Fireworks.
A tracing image is a JPEG, GIF, or PNG image that is placed in the background of the Document window. You can hide the image, set its opacity, and change its position.
The Page Properties dialog box appears.
To switch to another tracing image or change the transparency of the current tracing image at any time, select Modify > Page Properties.
The tracing image is visible only in Dreamweaver. It is never visible when you view the page in a browser. When the tracing image is visible, the pages real background image and color are not visible in the Document window; however, the background image and color will be visible when the page is viewed in a browser.
The tracing image returns to the upper-left corner of the Document window (0,0).
The upper-left corner of the tracing image is aligned with the upper-left corner of the selected element.
