Regularization images are created as .jpg, but moved as .png

[hsbsid]

Running the notebook on runpod, I did not have this issue until today.

!mkdir -p regularization_images/{dataset} !mv outputs/txt2img-samples/.png regularization_images/{dataset}

after regularization images are created, they are not moved to the regularization_images/{dataset} folder as they are all .jpg and this line moves all *.png

Is this a change in SD? Did it previously generate as png?
