The plugin is an attachment at the bottom of the very first post. Don't forget to read the updated first paragraph of that post and to download the LibFredo6 3.1f files, Fredoscale won't work without them.

I do exactly as Mut mentioned and it works every time for me, however I did have some issues in the first couple fo times I did it.
