Testing text and image preview

So I have this graph that I want to write lines and lines of text about. I inserted the image as the first thing.

It seems that I can insert the text above the image now which I couldn't do before which is pleasant so let's see if we can add oodles of text below as well

Here I am adding text at the bottom ! Life is really on the upswing. So I have an issue that asks us to use more lines of text in the preview. Is it even valid now?
Perhaps we need new lines.

Do you think that could be the case? Or when they say "preview" do they refer to the synopsis in the list of posts. Perhaps I have been barking up the wrong tree.
