Can’t put <br>s under images. removing text to the right

I’m working on a online painting course at http://paintingcourse.net . My images are are refusing to stand alone, and the text keeps popping up directly to the right of the image. As you can see this has created a disconnect from the image and the text to which it pertains. I’ve tried to put <br> before, and after, and enclosing the image code. (yes im also closing them) Also tried surrounding the image with <p> to try and seperate it from the text. Every time I edit, then hit save, all my new code vanishes. And yes, I do have it in code view, and not the visual view.

suggestions?

Where it says “Cad Yellow” should be under the image. Not to the right of it.
