# 12.3. Editing and Creating Images with the GIMP

The GNU Image Manipulation Program (GIMP) is a powerful application that can alter, manipulate, enhance, and create digital image files. FIXME discusses how to start the application. The following sections discuss the main features of the application.

## 12.3.1. Saving an Image

To save an image file, right-click on the image, choose File, and select either Save or Save As. The Save Image window opens. Navigate to the directory where you would like to save your file. Enter a name for your file in the field at the bottom of the window.

You must choose a file type for your image. By default, the GIMP will save your file according to the extension you type at the end of your file name. You may also select the file type from the Determine File Type drop-down menu above the file name field. When you are ready to save, click the OK button.

Depending on the file type you selected, another window with options may open. Ingeneral, it is a good idea to accept the settings that the GIMP suggests. Click the OK button again to complete the save process.
