The default is to stretch each picture to exactly fill the morph area as defined in the Timeline Options by the Width and Height settings.
Each picture has it's own Picture Layout window you can access under the Picture menu, available only in the Industrial edition. From there, you can select one of the two scale options to maintain the picture's aspect ratio, or the top option as well. The 4th option, which is the default, will stretch the picture and disregard the aspect ratio.
