But here I dont get the contact image of the user.The documentation says I need a contact id for getting the photo,but I dont get a contact id in the response above.How can I get the contact id of the user and subsequently his contact photo?
I have authorized the app using oauth 2.0 and apart from image I get most of the details of the contact.
EDIT: I tried this way from the documentation and it works,but it returns the binary image instead of the image URL and I have to send another request to get the image.
$url1 ='https://www.google.com/m8/feeds/photos/media/{useremail}/13444? v=3.0&oauth_token='.$accesstoken;
$xmlresponse1 = curl($url1);
To display the image:
<img src="data:image/*;base64,<?php echo base64_encode($xmlresponse1); ?> />
Can't I get the contact image URL something like facebook returns?

Answer 1

According the documentation, contactIid is returned in the contact entry URL returned by the API:
http://www.google.com/m8/feeds/contacts/<userEmail>/base/<contactId>
So, giving your sample:
http://www.google.com/m8/feeds/contacts/sfdhitdf1%40gmail.com/base/1
We have these values:
userEmail: sfdhitdf1#gmail.com
contactId: 1
