How do you make the pictures still in iMovie?

To add a freeze frame still image to a movie in iMovie move the mouse pointer over the image, in the project section, you wish to freeze and right click (or press the Control key and click) and select Add Freeze Frame from the pop up menu. This will add a 4 second still clip into the movie. Double click on the new clip to show the inspector and you can change the Duration of the clip or add an effect to the clip. Moving the mouse over the new clip reveals a small blue options menu in the bottom left corner of the clip. From this you can select Cropping, Ken Burns and Rotation with which you can crop, rotate or scan across the still image - for example to zoom in on a persons face.
