Adobe Photoshop is one of the most commonly used tool by designers in all fields such as web, printing, animation and UI design. Working with the Photoshop PSD files as source for design elements can help you get a quicker and more effective start. A PSD file is an image file created by Adobe Photoshop that may include image layers, adjustment layers, layer masks, annotation notes, file information, keywords, and other Photoshop-specific elements. The PSD files contain all the information and flexibility for being changed you could ask for.

While PSD files are saved in a proprietary format, they can be opened directly with Apple Preview, which is included with Mac OS X. They can be also opened by the media programs included with Windows 7 if the correct codec, such as the Ardfry PSD codec, is installed. These programs include Windows 7 Photo Viewer, Windows 7 Media Center, and Windows Media Player.
