I'm using pd-extended on os x, and I'm trying to use [pix_freeframe] but it doesn't seem to be included in extended. I downloaded FreeFrame FX for OS X (http://petewarden.com/#Free%20Downloads) but I don't even know if that's what I need or where it goes.

What download of pix_freeframe do I need and where do I get it?
Where do plugins go for Pd?

I've searched all morning with no luck!
