Is it possible to obtain the width of the textFrame when an image is positioned above it?

Sometimes my image isn't inserted into the text box; instead, it sits above textFrame
When I am only selecting the image, I want to retrieve the width of the text box.

If the text box isn't split into columns, retrieve the full width of the text box. If it is split into columns, retrieve the width of one column.

(or sometimes it may appear below the text)
Thank you.
