How to display Country Flags on participants?
In order to display the Country Flags on all pages that feature participants, you have to use the "Country" Custom Field and make sure it is 'Public'.
Also, make sure that you do not apply a logo to any participant, because the system can only display a single type of visual, either logos or flags, and logos have the priority. So if you upload a logo on a participant, it will only display logos for all participants, even though some of them don't have one, the flag won't be displayed.
