@midora Thank you so, so much, even 9 years later this really helped me!! It's like the most perfect, specific-to-what-I-needed tool/plugin! Especially since there is a glitch in paint.net, I tried to save a photo as a png, but I think it saved as a png with a .pdn file extension. I really thought I would have to make the whole file over again !!🥹
You're a genius, thank you for the work you do!!!
