Quick tip 17 � Resize an image

This is part 17 of the Photoshop quick tip series where you will learn how to resize an image. Resizing an image is useful for reducing the size of an image file. Note that increasing or decreasing the size of an image too much can cause the image to become distorted and blurry.

Firstly, open an image in Photoshop. Then in the menu bar choose Image > Image Size and the following window dialog will appear.

Now, changing the image size is as simple as adjusting the width and height of the pixel dimensions. By default the �Constrain Proportions� option is checked which means that if either one the width or height settings are changed. The other option will be changed to match the aspect ratio of the overall image file. However, if you want custom dimensions you can uncheck this option.
