<a href="http://www.pofableau.com/openlayer/multicouche2.html//" target="_top" rel="nofollow" link="external">here's</a> url of my test.
for adapt an size of an OpenLayers.Layer.Vector and an externalGraphic
I call a var zoom with map.getZoom
line: 159 I call var z= map.getZoom(); for change the size of an image
But they don't work "Error: Invalid value for <img> attribute height="Infinity"
