Get Image for GeoREST could not work

[GoogleCodeExporter]

Steps:
1. load samples data
2. set data source in GeoRest configure file
<Resource uripart="Parcels">
            <Source type="MapGuide">
                <FeatureSource>Library://Samples/Sheboygan/Data/Parcels.FeatureSource</FeatureSource>
                <FeatureClass>SHP_Schema:Parcels</FeatureClass>
            </Source>
            <Representation renderer="JSON" pattern=".json"/>
            <Representation renderer="PNG8" pattern=".png"><Method name="GET" />
                <MapDefinition>Library://Samples/Sheboygan/Maps/Sheboygan.MapDefinition</MapDefinition>                          
                <DefaultZoomFactor>1.3</DefaultZoomFactor>
            </Representation>
3. launch GeoREST server
4. send request to Rest Server
http://localhost:99/rest/data/parcels/.png?FORMAT=PNG&SETDISPLAYDPI=96&SETDISPLA
YHEIGHT=500&SETDISPLAYWIDTH=500&SETVIEWCENTERX=-87.73&SETVIEWCENTERY=43.72&SETVI
EWSCALE=2860 

Result:
Invalid stream header exception.
no image return.


Expected:
Request could get image from server
