Creating a Web Page in Dreamweaver 8: How to Add Images
Dreamweaver can handle basic image editing; for more demanding tasks use a dedicated graphics program. If you don’t already have a graphics program, take a look in the graphics section of www.versiontracker.com where you can compare prices, features, and user comments.
As with text-related tasks, the Properties inspector acts as your main tool for most image work. (See extra bits on page 45.)
