You may find that just letting it sit will allow the air pocket to get worked up towards the top and come out.
Otherwise make sure it's full put the cap on and go for a short drive then let it cool all the way again. Maybe that will do it. I've always just filled them up, ran it and let the thermostat open and circulate the water to get the air to come out so I'm not much help.
I have filled stuff up through the thermostat hole before then installed the stat and upper hose and topped the rad. off.
You need to take pictures from a closer vantage point, not all the way across the shop, either that or get a zoom lens. I'm old and don't like to strain my eyes to look at your GF. K Thx
