title: can i get a photo directlly from calllog.calls provider
body: <p>i want to get a contact photo (if he has one) from the callLog.</p>
  
  <p>now i know i can get the number and then query the contacts provider for a contact id.</p>
  
  <p>however i want to know if there is a better way one that directly get the photo uri from the callLog.calls table.
  what makes me believe it might be possible is the fact that inside the documentation i ran across 2 interesting fields:</p>
  
  <p>1)<strong>CACHED_LOOKUP_URI</strong> -The cached URI to look up the contact associated with the phone number, if it exists. </p>
  
  <p>2)<strong>CACHED_PHOTO_ID</strong> - The cached photo id of the picture associated with the phone number, if it exists. </p>
  
  <p>now if it can be done how, and if it cant be done than i would like to know what those fields are used for,
  thx</p>
