photos moving

Select the photo and then click on the crop tool (the one that looks like intersecting angles) in the toolbar at the upper right of your screen. In the settings controls that appear, deselect Ken Burns and select Fit.

For future projects, click on iMovie/Preferences and select Photo Placement: Fit in the preferences box that appears. Projects created after the change will not have the Ken Burns movement.

I forgot to mention for the first solution above, after you change your setting to "Fit" you next must click on the blue reset button to the right to apply the new setting.
