Check out the SDialogueNodeWidget::Construct function in DialogueNodeWidget.cpp
It has some comments as to what’s being done. Towards the end of the function you’ll find a comment that says “text block - displayed only when out of Editing mode”. The text block has to be wrapped into a horizontal box, where the first element is this text block, and the second element will be your image, just like you’d do in UMG. You start modifying the code after line 111. Good luck! Let me know how it went.
