Great news, however the the field where I should paste the verification code is not very obvious as it a little bitten hidden at first. You have to scroll down in the Connections window to find it. I finally did
I can confirm that the upload to Flickr now is working smoothless. I wish there where an option to create a new set or album directly from the File uploader dialog. I can upload it to a pre-made set/album with other images already in it. On the Flickr web page itsefl I cannot create an empty album.
If I understand it right the only way to accomplish this is to use the following process: 1. upload from PM5 to Flickr, 2. switch to a web browser, 3. enter the Flickr webpage, 4. create a new album, 5. and add the recently added images. Correct?
