Assembly presentation

Hey everyone, I have run into another problem on Solidworks. I have created an assembly of a sat nav unit on solidworks 2009. I wish to save a screen shot of this assembly and insert it into a word file. My problem is that when I save it as a jpeg file the resolution is very bad. I am not used to creating drawings so could anyone talk my through how to do this?
