Open your image in Photoshop.2)
Locate the 'Crop' button on the left hand side tool bar, click and hold until some more options appear, and then click on the 'Slice Select' tool when it appears.3)
Click on the 'Divide' button at the top of the screen (on the Slice toolbar)4)
Choose how many times you want to cut the image up, and what sizes you want them at. It should be set up to divide them all equally by default.5)
From there, you can alter the size of your images so that they are all multiples of 32 pixels. Or you can resize the image first, and then cut it up. So long as you don't need to enlarge the images too much, you shouldn't see any noticeable loss in quality.[/QUOTE]
