On advice from greater minds the way I found easy for me was to download an app. called dd-gui.app from http://www.gingerbeardman.com/dd-gui/ called : dd-gui-.zip
Once installed and opened on the mac. Download the Image file (Debian in my case).
Using dd-gui in the source line enter /Users/yourusername/Downloads/debian6-13-04-2012/debian6-13-04-2012.img
In the destination line /dev/disk1 and hit start.
A terminal should open showing that it is creating a file of 195000000 bytes.
This worked for me.
Thank you me brew
