s= Generate an HTML IMG tag for this image, with customization.
Arguments to self.tag() can be any valid attributes of an IMG tag.
'src' will always be an absolute pathname, to prevent redundant
downloading of images. Defaults are applied intelligently for
'height', 'width', and 'alt'. If specified, the 'scale', 'xscale',
and 'yscale' keyword arguments will be used to automatically adjust
the output height and width values of the image tag.
