Hacking → Protect Yourself

1. Use a no-right-click script.

   This prevents easy copying of pictures and easily viewing the source. Note: This can be circumvented by using Javascript.

2. Use frames.

   This prevents viewing of the source from the top of the page. Note: This can be circumvented by using browser history.

3. Encrypt the frames page.

   Encryption can stop hackers altogether. By using multiple encryption programs sources become unreadable. Note: Even encryption can be beaten.

As you can see none of these methods are fool-proof. If you are serious about protecting your code, but don't want to spend lots of money, and can use PHP, check out FreeLock PHP Encoder.
