显示图片后下拉右键回答javascript

Question

我有这个代码。目标应该是根据选择标签代码的值显示图像。(更详细的是，如果答案正确，显示"检查"图像，如果答案错误，显示"x"图像。我有一个基本代码，并在上面进行了大量修改和书写，但由于图像无法显示，我在这一步上遇到了困难。知道吗？：-？

function finalScore(round) {
var correct = 0;
var selectValue;
var questions = document.getElementsByClassName("question");
var numOfQuestions = questions.length;
for (var i = 0; i < questions.length; i++) { //begin for loop
//get the value of the select element
selectValue = questions[i].options[questions[i].selectedIndex].value;
//if the value equals right
if (selectValue === "corect") { //begin if then
//increment the correct variable
correct = correct + 1;
var img = new Image();
img.src = 'https://i.ibb.co/4JKs8RV/check.jpg';

} else if (selectValue === "gresit") { 
correct = correct + 0;   
var img = new Image();
img.src = 'https://i.ibb.co/XWSYMSg/wrong.jpg';      
} else if (selectValue === "gresit")
{ 
correct = correct + 0;
var img = new Image();
img.src = 'https://i.ibb.co/XWSYMSg/wrong.jpg';
} 
} //end for loop

if (round === false) {
//get the percentage of correct answers(not rounded)
document.getElementById("scoreDisplay").innerHTML = correct;
} else {
//display the rounded value
document.getElementById("scoreDisplay").innerHTML = correct;
} //end if then else
} //end function
