In details page , i am not getting the image just only shows the alternate text .

Your post isn't attached to any video or challenge, so it's difficult to know what this is about. When a value goes missing, you want to take a look at what is in the variable. When developing using something like var_dump($title) might be used to confirm that what is in variable is what you expect (if the value is missing and you haven't got the variable name wrong, you then work back to where the variable came from to see what went wrong). If the src is present, you might want to look at the path contained for src. My other advice would be that if this is related to a workspace, you can post a snapshot so people can help you debug. (see https://teamtreehouse.com/library/previews-and-snapshots)

A follow up. I ran the following

<?php
        //Enter your code here, enjoy!

$title = array("img" => "img\something.jpg",             );

?>
<div class="media-picture">
  <span>
    <img src="<?php echo $title["img"];?>" alt="" >
    </span>
  </div>

and got:

<div class="media-picture">
  <span>
    <img src="img\something.jpg" alt="" >
    </span>
  </div>

So the first step is confirm there is a variable called title containing a value for img. (Unless there is a value for src - but it is faulty)
