The box above your post is what is called the bread crumbs button. It’s where you can click anywhere along the string and go back to the page you were working on prior to this one. Just hover your mouse over the words and you will see.
Also a lot of people have been complaining that they cannot see where to post a picture. Look at the toolbar in this text and the last tool is the square with the mountain and the star in it. That is the button you click on to upload an image. I’m trying to get the developer to add a bigger button or one that stands out more than that for image upload. Hang tight.
