I'm relatively new to QGIS - I'm switching from MapInfo.
I'd like to have two separate maps in my print composer in QGIS. One the main frame linked to my canvas window and the other a raster image from OS mapping (an overview of the project). Screenshots attached of my current QGIS window and the MapInfo layout I'm trying to replicate.
I can't work out how to just bring my raster into the small map window at the moment.
