I want to keep image\_filter’s result to harddrive, and any one can help  
me to do it? Now I can only resize the original image.

Following code only does resize.

# image resize

location /pic {  
root /Users/alexgao/linux/web/dskb.cn;  
try\_files $uri @resize\_pic;  
}

location @resize\_pic {  
root /Users/alexgao/linux/web/dskb.cn;  
if ($request\_filename ~ [a-zA-Z0-9-]+_([0-9]+)x([0-9]+).jpg) {  
set $img\_width $1;  
set $img\_height $2;  
rewrite ^(.\*)_[0-9]+x[0-9]+.jpg$ $1.jpg break;  
}  
image\_filter resize $img\_width $img\_height;  
image\_filter\_buffer 1M;  
proxy\_store on;  
proxy\_store\_access user:rw group:rw all:rw;  
proxy\_temp\_path /Users/alexgao/linux/web/dskb.cn;  
}
