Locking relative position of wrapped text and picture?

[Red Marker]

I have used Format picture>Layout>Square+Left to wrap text around a picture
in the same column, but then if I add more text above the first text and
picture the first text is no longer aligned with the picture in the relative
position I had set it. How can I lock the relative position of wrapped text
to a picture?

Anchor the picture to the paragraph with which you want to align, and lock
the anchor.
