For the Rotators, the images must be the exact width and height or they will be scaled and cropped to the exact width and height which may distort the image.
For the Single Images and Image Galleries, the height and width are just the maximum value. Images will be scaled so they are no wider that the specified width and no higher than the specified height. There is no minimum values and images can be different orientations.
For images added through the editor, the width is just a maximum value. Images will be scaled so they are no wider that the specified width. Note that they will be distorted at smaller screen sizes unless you leave out the specific height setting in the image properties.
