Add a transparent border: Layer -> Transparency -> Add Alpha Channel then Image -> Canvas size
Apply the script Layer -> Transparency -> Bleed Colors into Transparent areas.
Edit
@Denarius As Ofnuts mentioned, you should really update to at least Gimp 2.10 (if possible) That gives more options such as this, using the gimp_gmic_qt plugin one of the many filters Frame -> Mirror. The size is a percentage, probably best to make oversize and crop down, but it is quick.
Thanks very much for the help. About using an older version, I'm on a very old computer. I will update soon when I get a new one.
After I posted, I tried again to do it in Paint.Net, and succeeded. I'm always trying both apps when I can't figure out how to do something in one app.
Thanks again for the replies.
