Q:

Facebook API upload photo from URL

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?

A:

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
