Hi,
I tried this mod and the pin it button appears, but it when clicking the pin it button it just shows an empty box and the URL in the pinterest.com pop up is just the home page directory...no product image
Tried the Numinix mod, but got as far as trying to install the SQL patch that throws the error:
ERROR: Cannot execute because table admin_pages does not exits. CHECK PREFIXES!

I am using 1.3.8, I'd really love to have a working pin it button...
