In Word 365, I edit scientific papers where most graphics (charts, usually) are not formatted as "Pictures". Instead, when selected, no Picture icon appears beside them, and Paragraph options are available. But occasionally, I get a paper where all graphics are "Pictures," several of which must appear side-by-side and are very difficult to position and to specify paragraph formats to them. They may appear over their captions or misbehave in other ways.

How can I convert a Picture into a non-Picture?
