Can anyone tell me where airnav radarbox puts the aircraft pictures it downloads please as i can not find them anywhere
Welcome. They're located in C:\Program Files\AirNav Systems\AirNav RadarBox 2009\Data\Photo - or wherever you installed Radarbox.
If you're running Windows Vista, then they'll be in the Virtual Store - C:\Users\xxxxxxxx\AppData\Local\VirtualStore\Program Files\AirNav Systems\AirNav RadarBox 2009\Data\Photo
