Linking avatar through Flickr

After Photobucket broke the internet I've signed up to Flickr (should have done a long time ago!). I can't seem to get my Avatar linked through it though. I assumed it would be a case of coping the "share" link and pasting it in the box in my profile but I get a message saying "The link entered is not valid."

This is the link I've trying to use, is it the right format?

Edit: Just realised it changes the format in the post! It's the same as above but with https:// in front of it.
