I was doing some photography with a 50mm equivalent prime and didn't want to go back to my car to get a wider lens for a shot that I was a bit too close to get the framing I wanted for. So I took 6 photos of the scene and stitched them together as a panorama with Hugin.

Turns out I was missing the bottom right corner and I had a big black square ruining the shot. So I took the post-processed panorama into GIMP, drew a crude outline of what I thought would be there and used StableDiffusion's Img2Img to generate the missing bit.

A little messy, but better than losing the image entirely.
(Unfortunately the image includes things that would get me doxxed instantly)

As for LLM's. Apparently GIMP doesn't have a bulk export function that exports all active images at once. So instead of exporting 140 images that I had masked for photogrammetry manually one at a time, I asked Bing Chat if it could make me a GimpFu script to batch export.

It gave me this:

from gimpfu import *

def export_all_images():
    for image in gimp.image_list():
        filename = image.filename
        if filename:
            new_filename = filename.rsplit(".", 1)[0] + ".jpg"
            pdb.gimp_file_save(image, image.active_layer, new_filename, new_filename)
        else:
            print("Image has no filename. Skipping.")

export_all_images()

which worked and saved me quite a bit of time.
