If you are seeking to copy an exact copy of a map page from one of your campaigns to another of your campaigns, there is a pro subscriber feature called " transmogrifier ". If it is a map that you uploaded to your campaign, it is in your art library and you can just load it from that. If it is built from tiles and is in your campaign, you will have to manually rebuild it or clone your campaign and include only map pages or anything else you want to copy. If it is from someone else's campaign then the best you can do is screen capture the map in sections without the grid on, stitch it together in a 3rd party program like gimp or paint, then upload it to your other campaign.
