I shipped a Squier to Greece once; I took it apart, wrapped it carefully and built a shipping case for it, from wood and hardboard. Heavy, but it did give peace of mind. I forgot to take photos though.
Also I shipped a guitar to Spain in April (acting for the buyer - Ebay seller wouldn't ship abroad). That was in a hard case. Buyer arranged insured UPS shipping via Interparcel. I bubblewrapped the guitar, put it in the hard case, layer of bubblewrap, put that in a guitar-sized cardboard shipping box, more bubblewrap, put the whole lot in a bass-sized shipping box, lots of tape with FRAGILE on it. I was very nervous, but all went well
