       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.
