The simplest solution - which MS should have implemented, IMHO - is to insert the image and caption in-line in a table (which you can apply text wrapping to) and to not allow the row/table to break across pages. For a macro to do that, see: https://www.msofficeforums.com/word-...html#post58886
Since you want the caption above the image, see also: https://www.msofficeforums.com/word-...html#post62610 (post #7 in the same thread).

Just a thought … but outside Word I work with a :fig_column style for the paragraph where the graphic is linked or inserted, keep with next, and a :figcap style for the caption.

A tutor taught me how to anchor the captions by grouping them with their pictures. So now the pictures float with them. Thanks, folks.
