Yes that's something we were working on as Drag and Drop doesn't seem to display content directly and it's hard to figure out why.
Other works on that in different languages often have the same behaviour.
Nevertheless if you D&D in Word, save as rtf and open it it with AHK RichEdit will work just fine.
BUT we have a solution to be able to Insert a in-place display object directly from the Editor.
And with that you can have all the different combinaison (Icon or Display, Embedd or Link !)

,
and how to convert the Autoit code ... 
Thanks for the hint on v2 though, I didn't start to use it yet.
