How can i make a JRPG dialogue system?

Hi! I’m seeing almost all of the tutorials are focused on ARPG system (one dialogue with some answers). I would like to create a classic jrpg dialogue system (character name, text and a image for the character who is talking). I have seen many tutorials and i’ve tried to modify some of them, but it’s impossible for me to get what i want sinvce i don’t know how to connect image and character with the dialogue text. Any help?
