Yay! I bet I'm once again the last person to notice it - but you can now DIRECTLY import photos from flickr to ipernity! All you need is FireFox and this Greasemonkey script: www.ipernity.com/about/gm
It works absolutely perfect! I started to import a first set of photos. Dunno if I will import all, but the possibility is simple and fascinating.
Thanks Ipernity for making me feel so much at home!!
