I am seeking to find why I can't up load to Flickr. Firstly I went into Publisher Services and set up my Flicka account I then came back into Lightroom and with my photos in Library I uploaded one into the photo stream after that I could not move any more images into Photostream. I had posted this question before and was asked to include a screen shot which I have done.
See if the link below helps which covers the following:
-Create a Flickr connection
-Add and manage photos in a Flickr photoset
-Upload to Flickr
