Change the images URI values within an array
I think you will have success with 

file_create_url("public://pizapuck.png");


so

for ( $i = 0; $i &lt; count($resultados); $i++){
  $resultados[$i]['uri'] = file_create_url($resultados[$i]['uri']);
}


would loop through your results and change them. (untested code typed directly in here).
