OK, I thought I'd try things out with a bigger challenge: converting a vertical image into a horizontal one! Specifically, this one:

This would require a LOT more generated image compared to just padding out the sides of an image that was already horizontal. Also, I was less strict with the A.I. In the previous image, I tried to only generate content that resembled what was already in the image, so as to better hide the fact that it had been padded out by A.I. This time, I thought I'd accept something if it looked good and made sense for what you would expect to be outside the borders of the original image.

Here's the results!

I think it looks a bit nicer than simply making the rear fence infinitely long. I dunno, I think the A.I-generated bamboo fence even looks a bit better! The original is a bit too straight, real bamboo isn't so perfectly straight! I also like the heavy snow piling up all over the place, the original image does indicate there's heavy snow coverage.
