So, break the string up into sub strings, seperated by +.
"<div id='Display' style='position:relative;width:100%;'>" +
"<img alt='Faces' src='im..." +
foo = "bar"; // foo is now set to "bar"
foo == "bar"; // (loose-equals) the answer is true, because the value of foo is equal to "bar".
foo === "bar"; // (equals) the answer is true, because the value of foo is the same as "bar".
So you clearly (to my understanding) meant to use the "=" operator out of the three possibilities above.
