Facebook API upload photo from URL

Question

I have a website with photo gallery and I'd like to upload each photo (one by one) to my facebook page (not wall). I managed to post a message but now I want to upload a photo to a FB Page Wall by uploading an existing image from the server - specific URL (I don't want to upload again locally). Is this possible?

Answer 1

Yes you can do it
Example In Graph Api Explorer
Make the call post, set url to https://graph.facebook.com/me/photos,
Add field with key message and value "any custom message"
Add another field with key url and value https://appharbor.com/assets/images/stackoverflow-logo.png
click submit

Answer 2

You need to know the album id and make call POST to:

https://graph.facebook.com/albumid/photos?access_token=$access_token

You will find the album id entering into the album and looking at the URL. Will be something like https://www.facebook.com/media/set/?set=a.XXXXXXXXXXX.YYYY.ZZZZZZZZZZ&type=3

Your album id are the XXXX.
