While Adobe Photoshop itself is one of the most important programs at any web designer's disposal, it's helpful to have the entire Creative Suite. Photoshop is ideal for creating and manipulating gorgeous pictures and page layouts, and in many cases it's all you need. However, Flash aids in creating top-of-the-line layouts with easy user interface and Adobe Illustrator helps you create fun moving GIFs or movies. Dreamweaver is perfect for crafting flawless websites, as well, especially when you don't want to rely solely on code. If you can only afford one program, stick to Photoshop, but try the whole Suite.
