I have finally got round to embedding a google map of the location of the church on our church website. This is a much better solution than just scanning a map from a roadatlas and uploading it (which breaks copyright law) or linking visitors to external sites, which may mean you lose those visitors.
I used the wordpress plugin called GeoPress. It is simple to set up once you have signed into Google and obtained an API key (Google Maps API registration). (Note: enter your blog url as the GoogleMaps URL).
Then you can add maps to any posts or pages, but most importantly for church website, to the map and directions page.
