Images cannot be shown in php - php

Question

I'm working on one webpage project and using php to show information of computers. I stored the urls of images in one relation and could successfully retrieve them out with php. But they cannot be shown in the webpage. Here's my code:
<?php
require_once('db_setup_hetty.php');
$sql = "USE hzhu24;";
if ($conn->query($sql) === TRUE){
//echo "using Database hzhu24"
}else{
echo "Error using database:" . $conn->error;
}
$C1 = $_POST["C1"];
$C2 = $_POST["C2"];
$query = "SELECT * FROM Items where Category1 Like '%$C1%' and Category2 Like '%$C2%';";
$result = $conn->query($query);
if($result->num_rows > 0){
?>
<?php
while($row = $result->fetch_assoc()){
$url = $row['Pic_url'];
?>
<div class="col-sm-4">
<div class="thumbnail">
<!--span class="e-label"><div>Sale</div></span-->
<span class="service-link text-center">
<img src= $url>
<div class="list-inline">
<i class="fa fa-eye"></i>
<i class="fa fa-link"></i>
</div>
</span>
<div class="caption">
<div class="category"> <?php echo $C2; ?>
<div class="pull-right">
<i class="fa fa-star"></i>
<i class="fa fa-star"></i>
<i class="fa fa-star"></i>
<i class="fa fa-star"></i>
<i class="fa fa-star-o"></i>
</div>
</div>
<h3><?php echo $row['Item_name']; ?></h3>
<h4><?php echo $row['Brand']; ?></h4>
<!--strong>$899.00</strong-->
<div>Details</div>
</div>
</div>
</div>
<?php
}
}
else {
echo "Item not found";
}
echo "</table>"
?>
And the webpage looks like:

If your php version >= 5.4, you can just use short echo tag like this:
<?php
require_once('db_setup_hetty.php');
$sql = "USE hzhu24;";
if ($conn->query($sql) === TRUE){
//echo "using Database hzhu24"
}else{
echo "Error using database:" . $conn->error;
}
$C1 = $_POST["C1"];
$C2 = $_POST["C2"];
$query = "SELECT * FROM Items where Category1 Like '%$C1%' and Category2 Like '%$C2%';";
$result = $conn->query($query);
if($result->num_rows > 0){
?>
<?php
while($row = $result->fetch_assoc()){
$url = $row['Pic_url'];
?>
<div class="col-sm-4">
<div class="thumbnail">
<!--span class="e-label"><div>Sale</div></span-->
<span class="service-link text-center">
<img src=<?=$url;?>>
<div class="list-inline">
<i class="fa fa-eye"></i>
<i class="fa fa-link"></i>
</div>
</span>
<div class="caption">
<div class="category">
<?=$C2;?>
<div class="pull-right">
<i class="fa fa-star"></i>
<i class="fa fa-star"></i>
<i class="fa fa-star"></i>
<i class="fa fa-star"></i>
<i class="fa fa-star-o"></i>
</div>
</div>
<h3><?=$row['Item_name'];?></h3>
<h4><?=$row['Brand'];?></h4>
<!--strong>$899.00</strong-->
<div>Details</div>
</div>
</div>
</div>
<?php
}
}
else {
echo "Item not found";
}
echo "</table>"
