So after searching, I found this

You have to be rooted to do this.
Using your favorite file explorer, go to system/media/audio/ui folder
Locate these files:
cam_start.ogg, cam_stop.ogg, camera_click.ogg, camera_click_short.ogg, shutter.ogg, shutter_multiple.ogg, and videorecord.ogg
rename the files and change .ogg > .old
After that you are done.
If you are a flashoholic, then you will need to do this after each flash of a rom as the files are fixed.
Takes ~1 min to do.
Thanks Nesto1. Your method is the best way for me.
To all those that said turn your phone to silence. It works only if you remember to turn it to silence in the first place, and afterwards you have to turn your phone volume back up. Way too much hassle, just use Nesto1's method and be done with forever...or until next firmware update.
Does not help if you're trying to take a quick pic of your dog doing something funny on his own...any sound will distract him and miss the chance.
