Whats the name of the site/person that provides video game controller pictures

With their internal parts. Like a blow-out picture.

You're looking for either the word "teardown" or possibly "knolling". Searching with those terms will give you a bunch of interesting disassembled controller pics. Are these the ones you mean? I think they used to be on ballenphotography.com, but I only see one of them left there now.

Or possibly these teardowns from Fictiv.
