I know that this question was raised out several times,
and I even read most of the questions regarding the topic.
But there was a gap of about a month till now, and I'd like to know if there is any process in changing the Timeline Cover picture from the api(via an app).
Do you know any new information about this?
Or is there a solution out there? (except for uploading to cover folder)
Thanks in advance.
In fact, there´s no API support for it, but you can upload a photo and then redirect user to: http://www.facebook.com/profile.php?preview_cover=PHOTO_ID
There is currently no API to change the cover photo; i'm not aware of plans to change this
facebook does not allow an app to upload a picture to the profile album. that is sort of a security restriction and will apply to cover images too, i guess. so you can upload a picture to a new album or any other album, but NOT the profile or timeline cover album.
i doubt that facebook will ever change this, unfortunately.
Profile Timeline is not yet released for all, so maybe we won't be getting any access via graph api until facebook releases timeline for all.
