IMG align none

I am sure it’s again something stupid. but I can’t seem to find it and have actually the same problem on 3 pages I run with the beautiful Zuki.
Img’s if not 100% have a strange behaviour. like here:
they just don’t align properly. I changed the margin and the size, what changed the behaviour but they never aligned. there are always some strange gaps. I am sure it’s something on my site, but can’t guess what it might be.

on this page i changed the padding of the main-entry but i have the same problem on all Zuki Run Pages.
