Just encrypt everything (including the pictures) and set the swf's to expire in a couple of months in case they don't pay their bill. Once paid you can upload new encrypted swf's again but obviously without the time restriction. It's amazing how fast clients pay their outstanding bills when the virtual tour stops working and is redirected to your own website

How many 360 degree images do you have for the full virtual tour? Is it just a few or an enormous tour?

Back up your entire tour folder 'twice' before you start encrypting anything. Once I forgot to back it up and after encrypting all the code I needed to go back in at a later date to make adjustments only to see random characters. That was a crap day.

Here's a post that has plenty explained.

Did I mention to back up the entire tour folder first before evening starting up the krpano Protect Tool.exe
