Body text is showing around the image which from the above image field

I encountered the same problem.

It depends on how you are adding the image. I am assuming that you are adding the image via ck editor and also with some text. So one solution is you can add some inline styling and add display block on the img tag and now image and text will be separated. Another option is you can attach a library for the page and write some css by targeting the class and you will achieve your desired results.
I hope this solves your query. If you want to know something else then please share
