I have a problem with the Facebook uploader in Picasa.How can I solve this (see below)?
Cannot upload photos from Picasa via Facebook uploader
facebook
I would definitely check the Picasa App permissions on the Facebook side. I was able to duplicate your findings after manually mangling the permissions the app got.You might need to remove the Picasa app first and then re-authenticate it via the Facebook Upload feature in the Picasa uploader.
