ive been working on my photo album and thought it would be nice to add my facebook albums to my shotwell collection because i know i have pictures on facebook i havent added into my photo collection yet. had a poke around and found a plugin for firefox called facepaste, installed the plugin and logged into facebook, then i went to photos and albums and scrolled down the page so i could see all the albums, then i right clicked and selected download facebook albums, i waited 30 seconds and the album names appeared which i selected and then selected the destination on the output side and then selected start and away it went!! ill just drop this into my shotwell collection then run find duplicates to get rid of dupes, great bit of kit worked a treat!
