1. Attaching a pic;
Instead of "quick reply" press "new reply" button, it will give you full interface.
Press "New attachment" button.
Browse to the pic, choose it, then press "Add attachment" button.
Once it is added below, press "place in text" (or something like it) button.
Press "post reply".
2. F-F means "filament to filament" that is a heater voltage.
3. Big pins (fat ones) are usually the Filaments. Those also serve as the key when inserting the tube, as fatter pins won't go into smaller pin sockets.
