My first guess would be the driver side has an exhaust leak, allowing air into the exhaust before the oxygen sensor. That would make the computer think that side is lean, and add fuel.

That you are awful at taking pictures. Put it on a sheet of paper on the ground so the camera will focus on it.

You need to mow, lol. I'm with Mike, re-tighten your manifold bolts and clean up, or get a new set of plugs, and check them after that.

they usually have an orange tint to them . . . if they're really black, then your tune is too rich. . . . but then again, that's not too bad if you have a NO2 tune
