Image alignment

In addition to image scaling you can alter the position of the graphic. The imagedata element accepts a align attribute to position the image horizontally. It takes a value of left, center, or right. The alignment is relative to the viewport area, which may be less than the whole page if you specify a width attribute. You can also use a valign attribute to position the graphic vertically within the viewport area. It takes a value of top, middle, or bottom.
