images instead of sprites for Yanfly's Visual Battlers

I'm using Yanfly's Visual Battlers script for my project. By default, this script shows actors using their overworld sprites. I would like to modify this script so that instead of showing actors with their sprites, it uses images instead, similar to the way actors were shown in Last Scenario.

This is an example of what I mean from the above.

I tried to look through the script myself to see if I could figure it out on my own, but I'm not a programmer, much less someone with knowledge of Ruby, so I just got lost. Is there a reasonably simple way to get this script to do what I want or will I have to find someone to write custom code for me? Information on how to include actor animations or at least different actor images for different skills, would be great, too, if you can provide it.

How are you going to define what images will be used?

Well, right now, my plan is to put all the images for the actors in separate file(s) and have the script put those on the battle screen in place of the sprites. I'd imagine it'd be similar to the way RPG maker puts images of enemies on screen during battle. Is that what you're asking?

So, I recently started looking at other scripts for alternatives/ideas and found exactly what I needed in CP's Battle Engine. The script includes five modes for displaying the UI; mode 3 is what I'm interested in. It works like this: a notetag in the actor or class' entry in the database specifies which image in the /Graphics/Battlers folder to display for the actor during battle.

What I'd like to do now is isolate this function from the rest of the script, since it breaks my UI. I'd prefer to graft the relevant code into Yanfly's Visual Battlers, if possible, so I can control where the graphics show up on screen. Can someone help me do that?
