In your js file you can do something like,

$.ajax({
    type:"POST",
    data:{opts: opts},
    url:"views/itemOverview.php",
    datatype: "text/json", // this is preferred when receiving json datasuccess:function(res){
      // res is json object. res.name & res.imageUrl are it's property
      $("#results").html("<p>Uw items : " + res.name + " <img src='"+ res.imageUrl+"' /></p>");
    }
  })
