Hi,
Is it possible to represent a point feature using some other customized shapes or a picture file or even a font symbol instead of using a WellKnownName as below? If yes, how can it be done? Any tutorials or examples?
<PointSymbolizer>
<Graphic>
<Mark>
<WellKnownName>circle</WellKnownName>
<Fill>
<CssParameter name="fill">#ff0000</CssParameter>
</Fill>
</Mark>
<Size>15.0</Size>
</Graphic>
</PointSymbolizer>
Thanks in advance.
Regards,
Wai See

It is definitely possible to specify an image in place of the regular shape markings. Here is a snippit of the xsd from the SLD spec:
<xs:element name="Graphic">
<xs:complexType>
<xs:sequence>
<xs:choice minOccurs="0" maxOccurs="unbounded">
<xs:element ref="sld:ExternalGraphic"/>
<xs:element ref="sld:Mark"/>
</xs:choice>
<xs:sequence>
<xs:element ref="sld:Opacity" minOccurs="0"/>
<xs:element ref="sld:Size" minOccurs="0"/>
<xs:element ref="sld:Rotation" minOccurs="0"/>
</xs:sequence>
</xs:sequence>
</xs:complexType>
</xs:element>
<xs:element name="ExternalGraphic">
<xs:complexType>
<xs:sequence>
<xs:element ref="sld:OnlineResource"/>
<xs:element ref="sld:Format"/>
</xs:sequence>
</xs:complexType>
</xs:element>
<xs:element name="Format" type="xs:string"/>
<xs:element name="Opacity" type="sld:ParameterValueType"/>
<xs:element name="Size" type="sld:ParameterValueType"/>
<xs:element name="Rotation" type="sld:ParameterValueType"/>
So what you need to use is the external graphic tag instead of the mark tag. In that tag there is the 'OnlineResource' which is the url relative to your styles directory in your geoserver installation directory, and the 'format' value which is the type of image file.
