Can some one explain this in a simpler way? I'm very confused:

"The energy released when a photon of light strikes a silver halide crystal frees an electron from the bromide ion. The former bromide ion is released from the crystal as bromine and is absorbed by the gelatin. The free electron moves through the crystal to a 'sensitivity speck' caused by imperfections in the crystal structure or created during the sensitizing process during manufacture. .This now negatively charged speck attracts positive silver ions which are neutralised to form silver atoms. If enough silver atoms form at a single point then a latent image is created. The latent image is not visible, even under a microscope so the only way to tell if it is present is to chemically develop the film to reveal the image."

also

"The atoms in a silver halide crystal exist as ions. Each bromine is a negative ion with an extra electron. Each silver is a positive ion with one electron missing. The combination, of course, has no net electrical charge.
During an exposure to light, a photon event occurs when an incoming photon knocks off the extra electron from one of the bromine ions. This photoelectron is now free and mobile, and it wanders about in its crystal until typically it finds a dislocation or flaw in the crystal lattice, where it becomes trapped.
A few of the silver ions are not locked in the crystal lattice, and these interstitial ions are also mobile. The negative electric field set up by the trapped photoelectron draws one of these positive silver ions over to it. When the two meet, the ion and the electron combine to form a neutral silver atom. This silver atom is the beginning of a latent image.
As the exposure continues, the same process is repeated several times until, in at least one place in the crystal, a compact group or aggregate of about four to six neutral silver atoms is eventually created. When this happens, a threshold is crossed. This clump of silver atoms is now large enough that it has become a fully formed latent image."

I just don't understand what occurs after the photon meets the silver halide crystal. Can someone explain it in a simpler way?

So, the whole thing, then.  I don't think we can really be more simple, and as through.  Try this:  write down each sentence, and see what each one means.  Maybe you can ask us ... what does this sentence mean, or you can compare what's been said to your textbook or your class notes.
