That's an older picture. I adjusted the Caster/ Castor (lets not get back into the argument over the correct spelling) late last night .easier to do that way for sure, but the load is dampened through the smaller joints on the drag link rather than the beefier wheel to wheel tierod. i can see your castor adjusters are still in the "0" position
I don't have my DIY alignment tools yet , so I just looked at the caster split between the two, maxed out the one that was closest, and kept the same approx spread with the other.
Here's what the caster adjuster looks like now (sorry for the poor pic quality)
