You need to provide the data as encoded binary of the image itself. The URL parameter only adds a link to the POST as a part of the text or annotation, it will not retrieve and add the photo istelf from that URL!
add something like
...
"url=" . urlencode(file_get_contents($photo_url));
...
And: furthermore the Method must be POST, I'm not quite sure whether "file_get_contents" is going to POST the data and not just doing a GET as the name imposes.
