# Note: The publish_actions scope is required to upload a photo.
$req->AddHeader('Authorization', 'Bearer FACEBOOK-ACCESS-TOKEN');
# Send an "Expect: 100-continue" header in the request.
# This causes the HTTP server to end a 100-continue response
# immediately after receiving the HTTP header. The client
# (Chilkat) will receive this intermediate response, and if
# it's not an error response, it knows that the HTTP server will
# accept the data that is forthcoming.
# The alternative is to get an error response after trying to upload
# the entire contents of the files.
$req->AddHeader('Expect', '100-continue');
# Set a photo caption.
$req->AddParam('caption', 'Here are some penguins!');
# Additional parameters can be added to the request by
# calling AddParam once per parameter.
# See https://developers.facebook.com/docs/graph-api/reference/user/photos
# for more information about other optional parameters.
# Indicate the local file to be uploaded.
