In order to display images first you have to create a c++ class that inherits from RichTextBlockImageDecorator. Once that c++ class is created, open it and look for the UCLASS() line in the header file and replace it with this UCLASS(Blueprintable, BlueprintType). Once you do that, click the compile button and once it completes you can create a blueprint child of the c++ class. From there, open the decorator blueprint you just created and you can add a richtextblockimagerow struct. The struct acts like the text one where you create a new row and add images to it with names as well as brushes. Finally you can add the decorator class into your richtextblock (from the decorator tab by pressing the +). Hope this helps!
