The computer I am viewing your pictures on won't let me enlarge them, but next to the starter it does appear that you have the standard fuse holder. The fact that your short in the lighting circuit did not blow the fuse, but instead shut down the operation of the car suggests that a blown fuse has been overridden with something such as a jumper wire.

That is only based on the description of the issue as I read it.
