Show images from database in Php/Mysql - php

Question

I try to make online quiz with images questions, and i need your help/advice.
My images is stored on database where have an id "image". My upload works fine, image is stored on database...but i can't show image in questions.
Here is my structure from database: http://imageshack.com/a/img923/8746/Kf16xl.jpg
And that's my code from show questions with image:
<?php
session_start();
require_once("scripts/connect_db.php");
$arrCount = "";
if(isset($_GET['question'])){
$question = preg_replace('/[^0-9]/', "", $_GET['question']);
$output = "";
$answers = "";
$q = "";
$sql = mysqli_query($connection, "SELECT id FROM questions");
$numQuestions = mysqli_num_rows($sql);
if(!isset($_SESSION['answer_array']) || $_SESSION['answer_array'] < 1){
$currQuestion = "1";
}else{
$arrCount = count($_SESSION['answer_array']);
}
if($arrCount > $numQuestions){
unset($_SESSION['answer_array']);
header("location: index.php");
exit();
}
if($arrCount >= $numQuestions){
echo 'finished|<p>There are no more questions. Please enter your first and last name and click next</p>
<form action="userAnswers.php" method="post">
<input type="hidden" name="complete" value="true">
<input type="text" name="username">
<input type="submit" value="Finish">
</form>';
exit();
}
if (!empty($image)) {
$sqlimage = mysqli_query($connection, "SELECT * FROM questions where 'image' = $image");
$imageresult = mysqli_query($connection, $sqlimage);
while($row=mysqli_fetch_assoc($imageresult))
{
echo '<img height="300" width="300" src="data:image;base64,'.$row[2].' "> ';
}
}
$singleSQL = mysqli_query($connection, "SELECT * FROM questions WHERE id='$question' LIMIT 1");
while($row = mysqli_fetch_array($singleSQL)){
$id = $row['id'];
$thisQuestion = $row['question'];
$type = $row['type'];
$question_id = $row['question_id'];
$q = '<h2>'.$thisQuestion.'</h2>';
$sql2 = mysqli_query($connection, "SELECT * FROM answers WHERE question_id='$question' ORDER BY rand()");
while($row2 = mysqli_fetch_array($sql2)){
$answer = $row2['answer'];
$correct = $row2['correct'];
$answers .= '<label style="cursor:pointer;"><input type="radio" name="rads" value="'.$correct.'">'.$answer.'</label>
<input type="hidden" id="qid" value="'.$id.'" name="qid"><br /><br />
';
}
$output = ''.$q.','.$answers.',<span id="btnSpan"><button onclick="post_answer()">Submit</button></span>';
echo $output;
}
}
?>
The part with show images is:
if (!empty($image)) {
$sqlimage = mysqli_query($connection, "SELECT * FROM questions where 'image' = $image");
$imageresult = mysqli_query($connection, $sqlimage);
while($row=mysqli_fetch_assoc($imageresult))
{
echo '<img height="300" width="300" src="data:image;base64,'.$row[2].' "> ';
}
}
Thank you very much for allocating your time!
