This function will solve your problem :

function checkRemoteFile($url)
{
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL,$url);
    // don't download content
    curl_setopt($ch, CURLOPT_NOBODY, 1);
    curl_setopt($ch, CURLOPT_FAILONERROR, 1);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    if(curl_exec($ch)!==FALSE)
    {
        return true;
    }
    else
    {
        return false;
    }
}

Just pass the image url in this function and it will return yes if image exists otherwise false

$file = "http://www.nasa.gov/images/content/711375main_grail20121205_4x3_946-710.jpg";
$file_headers = @get_headers($file);
if($file_headers[0] == 'HTTP/1.1 404 Not Found') {
    $exists = false;
}
else {
    $exists = true;
}

What if it's `HTTP/1.0`? There are better ways to check for this. Also, this _only_ looks at 404s. For the OPs case, it may be important that it's specifically a 200 response. No redirects, no authorization, etc. – Colin M Mar 18 '13 at 12:55

<?
$img = $row['blog_url'];
$headers = get_headers($img);
if(substr($headers[0], 9, 3) == '200') {
?>
<img src="<?php echo $img; ?>"/>
<?
} else {
?>
<img src="noimage.jpg"/>
<?
}
?>
