# This example requires the Chilkat API to have been previously unlocked.
# See Global Unlock Sample for sample code.

# This example assumes a previously obtained an access token

# Provide the authentication credentials (i.e. the access key)
rest.SetAuthOAuth2(oauth2)

# Indicate that we only want the photos the user has personally uploaded.
rest.AddQueryParam("type","uploaded")

# We could limit the number of photos by setting a limit.
rest.AddQueryParam("limit","5")

# Gets the 1st page of photos. (Not the actual image data, but the information about each photo.)
# See https://developers.facebook.com/docs/graph-api/reference/user/photos/ for more information.
