Using images for a Perchance generator?

So I have an NPC maker generator that's currently still in progress, but since they revolve around original species I've made, I thought about adding images that represent what they look like. But, I also want the images to match the description that has been generated (as closely as possible, as judging from the amount of lists I have, that might not be very ideal). How would I make this happen?

The generator is here: https://perchance.org/my-npc-makers
