Crop Tool, Slice Tool and Slice Select Tool

The Crop Tool allows you to crop your images to the desired size. Click, drag, press Enter and you just cropped your image. The cropping is best done at the end of the editing process.

The Slice Tool and Slice Select Tool are mainly for Web Designers and have very few uses for regular uses. How it works? Well, you drag with the Slice Tool and create rectangles (usually web pages layouts). After you’re done you select Save for Web & Devices from the File menu and select a folder. This process will save each sliced portion as a separate image thus allowing you to quickly use these images for website creation.
