with the pointer tool selected, choose the menu choice file, Import from the menu. choose the image you want, and it loads into a 1/2 square, ready to be placed. click left mouse button once in the upper left corner of the white box to place the image.
detail I forgot: when you are about to click and place the image, if you click and hold the left mouse button, you can drag the box and make the placed image whatever size you want by letting go of the mouse. that way, you don’t have to place the image at original size saving time resizing!
