I am trying to run OS X Mavericks from a 1TB external hard drive, but can't find an image to download/load on the drive, and don't know how to select the external drive as a boot device.
 
Solution
- plug in your external hard drive
- run the OS installer
- select external HD as drive to install.
Once the installation process is over
- start the computer and while it's booting hold Option or Alt
- a screan asking you which drive you want to boot from shoot popup

here are some help full keyboard shortcut: http://support.apple.com/kb/ht1343
It's exactly the same as installing to the internal drive in your Mac. Just select the drive as the destination drive during installation; it's as simple as that. Another way ist to clone your internal drive to an external one using SuperDuper. Just make sure that the drive is partitioned using the GPT scheme.
