I installed the other bits too Hagar, but as yet I've not copied over the thumbnail pics in the parent folder of the download.
Could you please just run me through how to get the selection 'icon-thumbnail' pics to where they need to be?.
So the aircraft come up with a picture instead of a "?" in the aircraft selection window.
I'm delighted that worked. What you need to do now is to paste those images into the Texture folders of the appropriate variation then rename them Thumbnail.jpg. (I'm not sure the one in GIF format will work but you could try it & see.) You can take screenshots of any that are missing & do the same with them.
