Add country flag to member list
 

I've added a custom profile field with country names, and I've uploaded country flag images to the server, and made all the appropriate settings in AdminCP. The member list does display a column for 'Country Flag' but no flag shows up, only the name of the country. I've tried various conditionals and variables, but can't find the right one(s). Even the few hacks from vb.org haven't worked. Can anyone help?
