php mapscript not saving raster layer,image blank

[Craig W]

I'm having a problem with the following script, it is just returning a
black square of the map size and is not loading the raster image
(correct directories have been deleted for mail):

// Load MapScript extension
if (!extension_loaded("MapScript"))
dl('php_mapscript.'.PHP_SHLIB_SUFFIX);
//create map object
$map_file="C:/La2/Inetpub/wwwroot/phpscripts/ap_wcs8bit.map";
$map = ms_newMapObj($map_file);

$img1 = $map->prepareimage();
$layer = $map->getLayerByName("ap040808_104124_vh");

// Render the map into an image object
$layer->set("status", 1);
$layer->draw($img1);
// Save the map to an image file
$img1->saveImage("C:/Lan/Inetpub/wwwroot/tmp/worldmap.jpg", $map);



Returns the following in the browser:
msDrawRasterLayerLow(ap040808_104124_vh): entering.

Returns no errors in php.log although i get the errors:
MapServer Error in :msSHPOpenFile()
(C:/Land2/Inetpub/wwwroot/phpscripts/ap040808_104124_vh_pwr_fil_geo.tif)
MapServer Error in :msSHPOpenFile()
(C:/Lan2/Inetpub/wwwroot/phpscripts/ap040808_104124_vh_pwr_fil_geo.tif)
If I attempt to do a getExtent() on the layer.

Mapfile (some sensitive metadata taken out) is attached.

The layers download fine in mapserver:

and within chameleon.

Anyone know what is wrong with my script, its for an OGC compliant
download service.

Hopefully I've given enough information.

Thanks,
