Load external images through PHP file (<img src="img.php?file=.."/>

Hi,

 

I've been reading through the Yahoo speed guidelines, and wanted to do something with the CDN suggestion. Meaning that I want to put my static content (images) on a subdomain. I'm now wondering how I can do this through PHP. I can of course change all my image src locations to <img src="http://cdn.mydomain.com/img/xx" alt=".."/>, but I rather have a PHP script get the images by having something like <img src="cdn.php?file=img.png" alt=".."/> which then loads the image from a server I specified in the cdn.php file (and thus can easily change). It will need to output a header() tag to have the browser recognize the image itself is coming from an external server.

 

I've been playing with a GD library to try to get this done, but I am starting to think I'm making way too much trouble of this. So I figured I would be best of here to check for other opinions .

 

Cheers!

well, if you know where it is you can use file_get_contents() to pull the image's code and then use headers to force it out as an image:

header('Content-Type: image/jpeg');
