[OSGeo-UK] Saving as a jpeg from QGIS print composer

Hi John

Caught this here - you might find there is a issue with output 
resolution.  The web service might not be able to generate an image of 
suitable quality of the resolution in print composer is set too high.  
try setting it to 100dpi and see if you get an image.

Can you save any image from composer?  do the shapefiles display on the 
map?  are the shapefiles using the same CRS as your base maps? I seem to 
recall a thread on the qgis-user mailing list about a similar issue.  
Other folk have reported problems with Print Composer and Open Layers plugin

These might help
* http://hub.qgis.org/issues/5827
* http://osgeo-org.1560.x6.nabble.com/print-composer-td5156773.html

I'll see what else I can dig out
