There are two options to see the nationalities of your visitors. First go to your GoPhoto - CMS and login with your credentials.
Dashboard
On your dashboard you find 'Visitors statistics'. Here you can see the top nationalities of your visitors over the past month. These numbers are taken from the languages of the webbrowser your visitor used to login to your Photo Website.
Statistics - Visitors
When you want to see an overview of the nationalities of your visitors over a different period of time go to 'Statistics' - 'Visitors' in the sidebar. Here you see a blue square that shows the top 3 top nationalities of that day. To switch dates you can adjust the date in the bar above the square.
Here you can change the date and get an overview over a different period of time. You can view these statistics daily, weekly, monthly or yearly.
