Hello Steven,
Thank you for the pointer.
It worked great once I re-projected from PostGIS. ArcInfo was giving very
bad results.

Best Always,

Hi Paul,
Since OSM and BING are both in Spherical Mercator projection and MapQuery
(nor the browser) can reproject images, the WMS has to be in spherical
mercator as well. It is possible to combine oms, bing and WMS, if they are
in spherical mercator, see:
http://mapquery.org/demo/widgets/mqLayerManager.html
If you zoom in you will see the Population_Density WMS appear, and you can
click on 'Add Bing aerial' to add the Bing layer.
Your WMS:
{
type:'wms',
label:'Parcels',
url:'http://gis.orchardparkny.org/cgi-bin/opopen.540',
layers:'parcel_poly_2008_4326'
}
Looks like an unprojected WGS84 (EPSG:4326) layer. This will not fit, you
could use a reprojecting tilecache like MapProxy to convert from that WMS to
Spherical Mercator or (even better) add support for Spherical Mercator to
your WMS and use that.
