Click on the image-> Format ->Text Wrapping

Good evening,
You can first add a container like an empty object (O1 below) (via <insert> <object>) a new powerpoint slide for example, and copy and paste your PPT element directly in it. resizing O1 = all elements are concerned

You also can use a single textbox (O2 below) (Insert>Form>).
Paste in O2 as Document Microsoft Word Object, objects (O3) coming from PPT.
Now right mouse click on O3: open; and a Word editable document can be gear

O2 can be resized around O3 without modifying O3.
You can resize O3 independently

Move O2 to move all and define properties of O2 to warp text around it

Regards
Patrice
