Hi. I want to include an image on my home page that is dynamically created from another website. The source code on a typical HTML page would be <img src="http://www.othersite.com/returnedimage.aspx"> I don't trust their server will always be up/respond, so I want to use a PHP function to determine whether a GIF has been returned (oppsed to an HTTP error) before sending it to the browser. Any recommendations how to do this?<img src="/image.php" /> image.php: <?php $image=file_get_contents('http://www.othersite.com/returnedimage.aspx'); if(substr($image,0,3)=='GIF') echo $image; else readfile('alternate_image.gif'); ?> -Rasmus
