What is wrong with my posts?

I’ve messed with several different themes and they all seem to have this odd issue and every time i post a new topic the images will change sides and the tables seem to break. I’ve tried to align them all to the left or leave them at none but they still will change. Any thoughts?

EDIT: After further tinkering it seems like it’s based on how big the text is in my initial post but what would cause it to go all screwy in my layout?
