Swapping the cat in a viral photo with one prompt

A pose from one photo, a cat from another. People keep asking how this was made, so here is the exact prompt.

OriginalAI version

Two images in, one image out

The trick is giving the model two separate jobs. Image 1 decides what happens: the punch, the angry face, the fisheye angle. Image 2 decides who it happens to.

Why it works

"Replace", not "make"

Asking for a replacement keeps everything else from image 1: the bed, the ceiling light, the photos on the wall, the wide-lens distortion.

One job per image

The prompt says which image owns the pose and which owns the cat. Without that, the model has to guess what to keep.

A reference sheet, not a selfie

Four angles on white show the coat from every side, so the model can draw the cat at an angle the reference never shows.

Where it ended up

It went straight onto a lock screen. Same punch, a different cat.
