Hi Pascal,
I don't see a transparent parameter in your uri. You might try
adding one to see if that helps. Not all wms servers will default to
transparent= true.
For example:
http://www.geocommu <http://www.geocommu nicator.gov/ wmsconnector/ com.esri.
wms.Esrimap? Service=WMS> nicator.gov/ wmsconnector/ com.esri. wms.Esrimap?
Service=WMS
&Version=1.1. 1&ServiceName= BLM_BASEMAPS_ wms&request= GetMap&layers=
blm_admin_
area_boundaries, usfs_forests_ boundaries& format=image/ png&transparent=
TRUE&sr
s=EPSG:4326& bbox=-126, 24,-66,50& WIDTH=1000& HEIGHT=433
I have had no problems using layers of <image> elements transparent png in
svg with IE+ASV or Firefox. Svg is actually quite a nice way to interface to
OWS services since svg can easily overlay multiple image elements from
WMS,WCS with vectors from WFS.

I think that a SVG UA 'should' be able to display transparent PNG, but
maybe ASV3 does not implement this in an image object. You'll have to
search/google, maybe there are known issues for ASV with PNG. You could
check this with a local PNG that you know has transparency, and load it into
ASV3. Also I think (but I am by no means a PNG expert) that there's several
flavours of PNG, like 24 bit and others.
Did you try getting the image from the WMS as GIF and see if that works...?
