Bandwith

guest

Hi i was wondering if i were to use the script

<?php
$id = $_GET['id'];

Header("Content-Type: image/gif");
$fn=fopen("./$id.jpg","r");
fpassthru($fn);
?>

which makes it print the image out of the php file... so if the php is printing the image would that mean that the php file is taking however big the picture is in bandwith?

ex: im hosting my images from another server(unlimited bandwith) but the php script that prints the image is on my server(has limited bandwith) would i run out of badwith if i showed all my images with the php script??

Yes, you would. And you'd probably run out of it quickly. By using this script you are telling your server to go to this other server and get the image (using bandwidth) and then send that image to the user (using more bandwidth). You probably don't want to do this. What you want to do is have the URL for the image be the other server that way the browser that is looking at your first page will read that URL and go directly to the image server and get the image thus not using your bandwidth.

ok seeing that.... if i were to do it would it also be taking twice the bandwith because first the server has to get the image from the server and then it has to print it out as its own image
so would that mean that its taking twice the bandwith than it should or would what im saying not be true??

I guess I wasn't clear. Yes you would be using twice the bandwidth by opening the file on the image server from your php server and sending it to your user.

What you want to do is publish the image links in the html that you php server generates that point directly to the image server this way the users browser will call for the image from the image server directly and not affect the bandwidth limitation on your php server.
