[Qgis-user] WMS service problems

Hello List,

Thanks to a recent post on slashgeo.org, I learned of some interesting data made accessible for the City of Toronto.  In particular, they list several WMS services inclucing Ortho Imagery.  You'll find them at the bottom of the list of the data catalogue (click the "Get Data" link at http://www.toronto.ca/open ).  I have been trying to load these data in Quantum GIS without any success...although I can get most non-imagery layers to load in ArcGIS.  I'd be wondering if anyone on this list is able to give the services a try, and if successful, perhaps explain what steps or settings I'm missing.

When I add the layers in Quantum GIS, I just get the layer listed in the legend, but no data in the map - it also seems that Quantum GIS is unable to detect the layer's extents.  I tried downloading one of the shapefiles from the toronto.ca data catalogue, and used that as a reference to make sure the map is zoomed to the correct location and still no luck.  I contacted the address listed in relation to the data in the catalogue, and in the reply I received, there is mention of setting an option to "Override WMS GetMap Pixel Limits" to 1024x1024, but this relates specifically to options within MapInfo.  Is there something similar that would need to be done in Quantum GIS?

Thanks in advance for any suggestions.

Mike
