To remove the heating element look at it from the front just like the way you took the photo.
Unplug the dryer.
Unplug the wires that go to the element. Then all you have to do is remove the one screw on the left side and the other screw on the right side of the element.
I can see the two screws you need to remove from the photo you took.
Let us know how it goes or if you have any other questions.
