Nginx + Plugin issue

Hi all,

i’m running a wordpress website on nginx, all working like a charm except with one of my plugin = Adaptive Images for WordPress. (This plugin serve scaled image).

The owner of this plugin said that, add this to location but it’s don’t works.

location / {
rewrite \.(?:jpe?g|gif|png)$ /wp-content/plugins/adaptive-images/adaptive-images-script.php;
}

Have also tried this:

location ~ /wp-content/(themes|uploads) {
     rewrite \.(?:jpe?g|gif|png)$ /wp-content/plugins/adaptive-images/adaptive-images-script.php;
}

and this:

location ~ /wp-content/(themes|uploads) {
rewrite \.(?:jpe?g|gif|png)$ /wp-content/plugins/adaptive-images/adaptive-images-script.php;
}

Nothing worked!

Here is my nginx config: https://github.com/stonedb00/stonedb/blob/master/nginxconf

So i need an nginx expert to give me the correct rewrite config and resolve it !

Thanks in advance
