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

* --------------------------------------------------------------------------------------------------------
* Note: The code for setting up the Chilkat REST object and making the initial connection can be done once.
* Once connected, the REST object may be re-used for many REST API calls.
* (It's a good idea to put the connection setup code in a separate function/subroutine.)
* --------------------------------------------------------------------------------------------------------

* It is assumed we previously obtained an OAuth2 access token.
* This example loads the JSON access token file 
* saved by this example: Get Google Contacts OAuth2 Access Token

* Connect using TLS.
lnBAutoReconnect = 1
lnSuccess = loRest.Connect("www.google.com",443,1,lnBAutoReconnect)

* Provide the authentication credentials (i.e. the access token)
loRest.SetAuthGoogle(loGAuth)

* ----------------------------------------------
* OK, the REST connection setup is completed..

* To upload a photo for the contact, send the following:

* 	PUT /m8/feeds/photos/media/default/contactId
