Thanks jackie_w,
Maybe a bit of a noob question, I've installed the plugin ok and even changed the settings on it, But where in Calibre is it supposed to show up to copy the cover to my Nook STR ?
I'm guessing right click on book and it should show an option ? Can't seem to find it though, I've restarted Calibre as instructed but still can't find it, I also read about settings in the "tools" section and adding it but it doesn't show the cover plugin

Thanks.
