I just used the defaults to make sure it worked. Only thing I changed was the pole width. Gif animations are usually small images due to file size, this one starts as 300 x 200 . example: https://i.imgur.com/GHK71I8.jpg Other image sizes might need different settings.
Exporting to a gif ? I think delay best increased. I used this: https://i.imgur.com/1Obk7bO.jpg

Edit: If you are really using Windows 32 bit and a Gimp 2.10.12 or earlier, the script should work ok.
If using Gimp 2.10.14 (which might not work with Win10 ) then some old Windows Gimp plugins are needed bump-map.exe and displace.exe
