    smallimagewidth, mediumimage, mediumimageurl, mediumimageheight, mediumimagewidth,
    largeimage, largeimageurl, largeimageheight, largeimagewidth.

    For example, [amazon 0596515804 title] will provide the title of the item, and
    [amazon 0596515804 largeimage] will be replaced with an img tag giving the large image.
