I would like my application to upload photo to a specific album of my friend. photos.upload(); can take albumid and userid as parameters, but it says "invalid albumId" whenever I try to upload it into my friends' albums, where as it successfully gives out the pictureId if it were to upload in my own Albums.
This isn't possible. There is no permission combination that will allow this. You can only share photos on the wall/timeline of the friend.
