Cropping an image allows you to decrease its size by cutting out parts of the image. Please read the following in its entirety before continuing.
This script takes place in two steps.
The first step requires you to upload the image from your computer to the site so it has the information needed for you to crop it.
Then, with help from Jcrop, you can visually select the area of the image that you want to crop out. For your convenience, you can see what the new height and width of the image will be. When you are ready to crop, just click the crop button and the server does the rest.
