Now you are ready to begin working on your image in earnest. While the big version on your screen is easy to see, keep in mind you will be e-mailing or Web posting a smaller version. That means every pixel counts, so you should check to see if there is unnecessary background that can be cut out of the photo. Odds are, there is some.
On your toolbar, look for the symbol for the cropping tool, which is a sort of a square with a line through the middle (and the third symbol from the top, on the right, in the screenshot here). If all else fails, float your mouse over the symbols until you see "Crop Tool." Click that symbol, and then click on the top left part of your photo that you want in the new cropped version. Stretch the mouse down and right until the proper area is highlighted.
If you mess up, just click on another symbol in the toolbox, and then on the crop symbol again. Once you have the proper area highlighted, click "Image" in the top line, and then "Crop."
