It should work. Here to see:

Betreff: Re: AW: [OpenLayers-Users] Simple KML layer help
Now have another problem. This kml file displays just fine at google.
But using OL the layer/icon does not show up:
<?xml version="1.0" encoding="UTF-8"?>
<kml xmlns="http://www.opengis.net/kml/2.2">
<Document>
<Style id="sh_sunny_copy70">
<IconStyle>
<scale>1.4</scale>
<Icon>
<href>http://maps.google.com/mapfiles/kml/shapes/sunny.png</href>
</Icon>
<hotSpot x="0.5" y="0.5" xunits="fraction" yunits="fraction"/> </IconStyle>
<LabelStyle> <color>ff00aaff</color> </LabelStyle> </Style> <Placemark>
<name>MY POINT</name> <description>My Point</description>
<address>101 Elm</address>
<Point>
<coordinates>-97.14879049,32.89119839, 0.</coordinates> </Point>
<styleUrl>#sh_sunny_copy70</styleUrl>
</Placemark>
</Document>
</kml>
Any suggestions???? I'm using the same code below. Note that the very same
script but with different lat/long works just fine in OL.
