Images on Pages won't align properly

I’m using the Freak theme, and need to include an image, right aligned, within the body of the text on the page. When I insert the image using the Editor I can set the right alignment and is displays there correctly, but when I view the page the image is still left aligned and the first line of text is next to the center of the photo rather than at the top. What do I need to do to get around this issue?
