Problem adding raster

[KevinDunlop]

Hi,

I have a few image services in my ArcGIS server and would like to add them to my web map in the SLV.  However when I do so the background (areas with no data) comes in black and completely covers any base map.  Is there a way to make areas beyond the edge of the raster (no data values) be transparent so that the base maps are visible?  Thanks,

Try setting the image format to pngjpg in the map.xml file

<esri:ArcGISImageServiceLayer ID="4f2c370288a54630b1299844e6f6414f" Visible="False" Url="<yourservice>" ImageFormat="JPGPNG">

If the transparency is set properly in the image service (and you are running arcgis10) it should fix the issue.

Thanks,
Jeff
