    // 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
    oauth2 := chilkat.NewOAuth2()
    oauth2.SetAccessToken("FACEBOOK-ACCESS-TOKEN")

    // Connect to Facebook.
    success := rest.Connect("graph.facebook.com",443,true,true)

    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.
