Front door sticking. Help!

[stucks123]

I know this is a very basic problem but we are having real problems with our front door. The door is sticking now that the colder weather has come in and despite us trying to adjust it we still have an issue.

I have adjusted the height up to the maximum but it kind of jams when it gets to closing (or opening) point and needs a bit of a shove. It's definitely not right.

I've attached a picture of the hinges, is there any advice/guidance anyone can give? Even towards a youtube video or similar which might help us with adjusting the door? Perhaps you can confirm from the picture the type of door/hinge we have to assist us with searching online?

Pics of door might help as well as telling us where the door sticks?

I've raised the height as much as I can.

There seems to be a small gap between the door and the frame at the bottom right of this picture (not visible on the picture)
