Putting the graphic inside the textsymbolizer the label does appear on top of
the graphic. Otherwise, try the other option instead: two symbolizers for the
polygon both generating a point geometry. You may want to calculate the point
geometry of the polygon beforehand in the database to be sure the same point is
used for both the TexstSymbolizer and the PointSymbolizer. With the proper
displacement values, this should work okay.
This is a piece of SLD I used for a table with railway stations with a point
geometry. It draws the label above the station icon

Edward,
Both options works for me, but labelplacement seems to be NOT working in both
cases. Label appears just over the image. Is there any way to fix
labelplacement ?

Hiya,
Check out the interiorPoint function as discussed in this thread
http://permalink.gmane.org/gmane.comp.gis.geoserver.user/33677. Thus, you
explicitly define a point geometry to be used to position the graphic and the
label.
Also, you can reference a graphic inside a TextSymbolizer, an approach
typically used for creating highway shields:
<TextSymbolizer>
<Label>
<ogc:PropertyName>NAME</ogc:PropertyName>
</Label>
<LabelPlacement>
<PointPlacement>
<AnchorPoint>
<AnchorPointX>0.5</AnchorPointX>
<AnchorPointY>1</AnchorPointY>
</AnchorPoint>
<Displacement>
<DisplacementX>0</DisplacementX>
<DisplacementY>-10</DisplacementY>
</Displacement>
</PointPlacement>
</LabelPlacement>
<Fill>
<CssParameter name="fill">#000000</CssParameter>
</Fill>
<Graphic>
<ExternalGraphic>
<OnlineResource
xlink:type="simple"
xlink:href="file:///C:/Subramanian/reficons/park.jpg" />
<Format>image/jpeg</Format>
</ExternalGraphic>
</Graphic>
</TextSymbolizer>

Edward

Subject: [Geoserver-users] Polygon label with graphic
Hi,
I have a polygon layer, which I want to label it WITH a jpg file. I am NOT able
to display jpg file and label along with it. Label and jpg is appearing at
different place on the map.
Is it possible to label polygon with jpg file ?á
Following is the contents of sld file,
