title: ABPersonSetImageData works fine but contact's photo doesn't sync with Google
body: <p>I've develop an App which set an image to my contact. It's working fine, my contact has the correct image in the iPhone AddressBook App.<br>
  I sync my AddressBook with Google and my contact's image doesn't sync with Google.<br> 
  Why?? If I set an image using Edit in the AddressBook it's working fine?<br>
  What I'm doing wrong??<br>
  Cheers and Merry Christmas.</p>
  
  <p>imgEscollida is and UIImage with the right photo contact to set.<br></p>
  
  <pre><code>ABAddressBookRef addressBook = ABAddressBookCreate();
  
  ABRecordRef record = ABAddressBookGetPersonWithRecordID(addressBook, personaID);
  
  if (record!=nil) {
      CFErrorRef *error = nil;
  
      ABPersonSetImageData(record, (CFDataRef)
                       (UIImagePNGRepresentation([self imgEscollida])), &amp;error);
  
      if (ABAddressBookSave(addressBook, &amp;error)) {
          NSLog(@"%s saved successfuly", _cmd);
      } 
      else {
          NSLog(@"%s something bad happen while saving", _cmd);
      }
  }   
  CFRelease(addressBook);
