Need to Save Resources, Will Redirect Help?

I have a MySpace Resource site. The images are one server and the site is on another. My image server is fine. But I am taxing my front end server.

Over a quarter of my bandwidth is taken by one image. I have moved it to my image server but the code is on thousands of sites and can't be moved. Future sites will call from the new location but what to do about those out there?

Will an htaccess redirect work and will this task the server more than simply serving the image?

 

The redirect won't affect system resources...even minorly.

 

how is this:

RewriteEngine On
RewriteCond %{HTTP_HOST} ^domain.com/img/button.gif [NC]
RewriteRule ^(.*)$ http://www.newdomain.com/img/button.gif [R=301,L]

Code (markup):

 

WOOHOO!

Here is what worked

Redirect 301 img/image.gif http://www.newdomain.com/img/button.gif

Code (markup):

 

Yep...that's the one-liner
