Images Of Different Aspect Ratios

I have images from various vendors which of which are differently proportioned than my standard size images from my won photography. Will CS-Cart simply resize them proportionally to fit? I don't want them to brake layouts or appear all distorted because of improper scaling. Where are any settings to control this and insure images will display correctly? Thanks for any insights.
