No, unless the game already knows to look for an image when those particular scenes are triggered. To reiterate what I stated, the game has to know that when such and such scene procs, it needs to look for an image to show along with the text as normal for images to show up. If it doesn't know an image needs to accompany the text, it won't matter how many images you have in the image folder, that scene will always just show text regardless. I could be wrong about this next part, but I'm pretty sure Kitteh is the only one that can go into the Revamp's code and add support for scenes to trigger showing images from the image pack, though once that's done, the player can change and modify what image shows just not when and where.
So, if a scene already shows an image, then yes you can change or edit the image pack to show a different image if you want. But you can't change what scenes proc images, since that requires under-the-hood code work. So if that scene doesn't already have a image associated with it, there's nothing you can do to force it to show one on your own.
