Inserting an image is performed like inserting any other graphical element using the menu entry to start the process, then selecting the file, and finally using the mouse to place the image above the worksheet.
Inserting an image starts by selecting, in the Insert menu, the Image menu item using the mouse cursor and the primary mouse button. This will open a dialog in which the user can select the file which contains the desired image.
In the dialog which appears the user must select the file which contains the desired image. The dialog will be specific to the particular operating system platform but should provide a way to navigate the filesystem to pick the folder that contains the file and have a way to select the file or type its name. When these choices have been made, the dialog can be dismissed by double clicking on the file or by clicking on the Open button. This will dismiss the dialog and expose the worksheet, with the mouse pointer now converted to a thin cross-hair.
The image, which will float like other graphical elements above the worksheet, must be placed on the worksheet. The image can be placed with its default size by moving the thin cross-hair pointer above the worksheet and clicking with the primary mouse button. Alternatively, the image can be placed and sized by selecting two of the resulting corners. This is done by moving the thin cross-hair pointer over the worksheet, determining one corner by clicking and holding the primary mouse button, dragging the pointer to the opposite corner, and releasing the mouse button. The image will then appear between the place where the primary mouse button was pressed and the place the button was released.
