Dreamweaver??™s Tracing Image function enables you to use such images to guide the precise placement
of graphics, text, tables, and forms in your Web page, enabling you to match the original design as
closely as possible.
To use a Tracing Image, the graphic must be saved in JPG, GIF, or PNG format. After the Tracing Image has
been placed in your page, it is viewable only in Dreamweaver??”it will never appear in a browser. A placed
Tracing Image hides any background color or background graphic in your Web page. Preview your page in
a browser or hide the Tracing Image to view your page without it.
If you??™re concerned about your page validating, be sure to remove the Tracing Image after
you??™ve completed the page. The Tracing Image uses a number of attributes, like tracingsrc
and tracingopacity, none of which validate, inside the tag.
Adding the Tracing Image to your page
To add a Tracing Image to your Dreamweaver page, choose View ??? Tracing Image ??? Load. This brings up a
Select Image Source dialog box that enables you to select the graphic to use as a Tracing Image. Clicking
Select brings up the Page Properties dialog box, shown in Figure 11-21, in which you can specify the opacity
of the Tracing Image in a range from Transparent (0%) to Opaque (100%).
