I've followed the instructions for creating user icons / overlays found in the Network Atlas guide. The graphic files follow the naming convention, they're GIFs and they're locaed in C:\Users\(username)\AppData\Roaming\SolarWinds\NetworkAtlas\Maps\Orion\localhost\NetObjects\User Graphics. However, when I open Select Graphic Image and click on the User Graphics section, there's nothing there. What am I doing wrong? Thanks.
