图像不显示或仅在本地显示

Question

I would like to display some images which their URL is saved in DB, but the images are not diplayed and when I right click on the image and select "view image" I see this message:

http://localhost/imdbImage.php?url=http://ia.media-imdb.com/images/M/MV5BMjExNzM0NDM0N15BMl5BanBnXkFtZTcwMzkxOTUwNw@@._V1_SY317_CR0,0,214,317_AL_.jpg cannot be diplayed because it contains errors

This is my code:

<?php
while ($row = $query->fetch(PDO::FETCH_ASSOC)):
?> 
    <tr>
       <td><img class='imdbImage' id="image" src='imdbImage.php?url=<?php echo $row['posterLink']; ?>' alt="" /></td>
       <td> ....
       ...
    </tr>

Also, I see this warning in php error log:

PHP Warning: file_get_contents(Null): failed to open stream: No such file or directory in /var/www/imdbImage.php on line 6, referer: http://localhost/movielist.php

while imdbImage.php is:

<?php
header("Content-type: image/jpeg");
//URL for IMDb Image.
$url = rawurldecode($_REQUEST['url']);
echo file_get_contents($url);   //THIS IS LINE 6 //
?>

When I try with the following code, it only shows the images locally. <td><img class='imdbImage' id="image" src=<?php echo $row['posterLink']; ?>' alt="" /></td>

Could someone kindly let me know what is the problem with my code and why the images are not shown?

Thanks

OMG! The problem was solved only by removing one blank line!!!

I wrote <?php in imdbImage.php file in the second line.. so the first line was empty. I found the solution in this post (Thanks to Johan)

You must not output anything before header(). Just start your document with <?php followed by the code for displaying the image. Skip the html tags. Do not even write a single blankline before header().

Hope it would be useful for someone else too :)
