Question: I was wondering if anyone knows of a free WMS of imagery that I could use within QGIS. The imagery does not have to be high resolution (Blue Marble even). I would like to have a base imagery feed from a WMS.

Any help would be appreciated.

Thanks...

Answer: 
You didn't specify which topic your WMS Feed should cover, but have a look a the website [mapmatters.org](http://www.mapmatters.org/).
They have a very extensive database with WMS servers connections that you can query.

Also the Openlayers plugin provides nice background images from Google Maps, Bing & Co.
You can get various WMS imagery layers for British Columbia (landsat, spot, ortho) from [DataBC](http://www.data.gov.bc.ca/dbc/catalogue/index.page?keywords=&config=dbc&sortid=4&rc=1&index=0&index=0&size=25&P110=resType%3aWeb%20Service). You didn't specify a geographic location.
