   Perhaps you could create an xml file with tags

<images>
	<image>
		<name>a.jpg</name>
		<width>640</width>
		<height>480</height>
	</image>
		.
		.
		.
</images>

or something.  You could automatically compute this with a script using
imagemagick's identify or the file command in linux.  Then in your xsl
file you could just declare a variable like

<xsl:variable name="width"
select="document('images.xml')/images/image[name='a.jpg']/width"/>

and use the width and height variables to decide how to rotate the image.
