<Style>

            IMG {put common attributes in here,

                        such as if they both won't have a border}

            .thumb {put style attributes in here that are only

                        associated to the thumbnail pic, which will

                         more than likely be width and height}

            .fullsize {put style attributes in here that are only

                        associated with the full pic - I think if you

                        eliminate the width and height attributes from

                        the IMG, you will get the default size which

                        should be the largest}
