Web pages integrate lots of different elements: GIFs, JPEGs, links, colors, and Flash and Shockwave movies, to name just a few. In a large site with lots of files, it's a challenge to locate a particular image or remember an exact color.
To simplify the process, Dreamweaver provides the Assets panel. For want of a better generic term, Macromedia defines the term asset to mean any element you use on a Web page, such as a GIF file, a link, or even an individual color.
Dreamweaver lists your site's assets on the nine category "pages" of the Assets panel (Figure 13-13). To open the panel, choose Window → Assets, or press F11.
You select an asset in the list by clicking its name; a miniature preview appears above the Assets list. To preview a movie, click the green arrow that appears in the preview window.
The Assets panel highlights nine different categories of site elements. To view the assets in a particular category, click its icon at the left of the Assets panel:
The Images category lists all of the GIF, JPEG, and PNG files in your site. Dreamweaver 8 lists the dimensions of each image next to its name, so you can quickly identify whether logo1.gif, or logo2.gif is your 728 x 90 pixel banner logo. You can also see the images' sizes, types, and where they're located in the site (you may need to scroll to the right to see all of this information).
