WMS Genève

Hello, I’m trying to use the Geneve Orthophoto with JOSM. I have tried the adress indicated here: http://wiki.openstreetmap.org/wiki/SITG_WMS , but it does not seems to work. May you tell me what should I use ? I have been able to use the Neuchatel Orthophoto, but I need the Geneva one.
Thanks a lot.

For those who are interested, an other Geneva user as given me the solution:
It is necessary in JOSM option to choose the “Grille Suisse” projection.
Then, still in JOSM option, in WMS, to configure a new photo, with the following URL: http://etat.geneve.ch/ags2/services/Orthophotos_2009/MapServer/WMSServer?version=1.3.0&layers=0&request=GetMap&styles=default&format=image%2Fjpeg&crs=EPSG:21781&

Hope this helps.
