Addon Script for ipernity import needs to be installed.

Be sure to change url on flickr from 'albums' to 'sets'

Be sure to refresh the album page with an F5.

Be sure to run the script twice.
First time it imports the photos in the album to ipernity (and creates the album there, but with only photos that were on ipernity prior to this first script run).
Second time the script will place the photos that are now on ipernity into the album there.
