Before beginning work with any design, you should define a new site in Dreamweaver.
Create a new folder named Simpsons and save it anywhere you like (for example, to My Documents, the Sites folder, or the Desktop).
Create a pics folder under your root (Simpson folder).
Download the sample files for this lesson, unzip them, and copy them to the new pics folder.
In Dreamweaver, choose Site > New Site.
Select the Site tab in the Site Definition dialog box. Type in a Site Name (Simpsons).
Navigate to your Local Site Folder you created above.
Click the Advanced Setting tab and select Local Info. On the Default Images folder navigate to your pics folder you created under the Simpson root folder.
Click OK to close the Site Setup for Simpsons dialog box. You now have defined you site. Make sure you save all your web pages to the Simpson folder and all your pictures/graphics to the pics folder.
