If an image is too large, or if you want to only incude one part of an image, you can crop or resize the image.
Cropping an image is like trimming off part of a picture. You can generally only crop rectagular areas (there is a more sophisticated technique, called masking, which allows non-rectagular cropping).
Resizing simply makes the image smaller, but doesn't remove any of the image content. Resizing is not the same as compressing and image, which makes the file size smaller but leaves the image size intact. Resizing can be constrained or unconstrained ("free"). Constraining keeps the image proportions the same (if you change the height, the width changes by the same amount). This option is also called "preserve aspect ratio." Unconstrained resizing or transforming allows you to change thge overall shape of the image. You are still limited to rectagular shapes however.

|
| And a cropped version: |
|
| In your graphics editor, select the Crop Tool. |  |
| The tool will form a selection rectangle; anything outside the rectangle will be cropped out of the image. |  |
| Once you've selected the crop, hit Return. |  |
Resizing an image simply changes the proportions of the image.
| Open the image in your graphics editor, and choose Modify --> Image Size from the menu. |  |
| If you want the image to maintain the same proportion, check "Constrain" oe "preserve aspect ratio" (Generally, this is selected as the default). |  |
| Change the dimensions. In the example, I selected 250 pixels as the horizontal dimension; since I had "constrain" selected, the program set the vertical dimension at 200 to maintain the same relative proportions. |
