I'm using Drupal 6 along with Gmap module. For some search functionalities, which I would like to implement using Gmap, I need to have markers for some countries presented on a map.
For example, on front page, I want to display world map with markers for UK, Ireland and New Zealand. Is there a way to somehow achieve this?
It's not entirely clear what you would like to achieve, but with the Location module you could associate Location data with nodes and later use that data for displaying on a Gmap (for example in a view). The Location module provides a Location field that you can use in your own content types.
I did the same for displaying user locations with the same toolkit and it's working well.
