I do not have a access to a physics lab, nor have I come across this type of a double slit experiment, hence I am curious if someone has tried this.

Given a double slit experiment setup with a detector. What happens if we have a detector at one of the slits, but we do not send one photon at a time (in other words, we send a bunch of photons without concerning ourselves about the count)? 

My assumption is that we will see a particle (bullet) pattern like we would if we sent one photon at a time, is this correct?
