Rewrite url to sub domain in NGINX - url-rewriting

Question

I currently have a image being outputted by server side PHP at a url like this:
domain.com/m/image.jpg
I'd like to have this image viewable at the url:
i.domain.com/image.jpg
Is this possible in the nginx conf?
Note: I currently have my "i" subdomain remapped to a /images/ folder.
Also I'm currently serving static images like the following:
http://i.domain.com/simage.jpg (thumb)
http://i.domain.com/image.jpg (medium)
http://i.domain.com/oimage.jpg (full quality)
Here's my domain.conf file: http://pastebin.com/BBWUJFxu
Also within nginx.conf I have this for the subdomain currently:
#setup subdomain i.domain.com
server {
server_name i.domain.com;
access_log /var/log/nginx/i.domain.com.access.log;
error_log /var/log/nginx/i.domain.com.error.log;
root /var/www/domain.com/html/images;
index index.php index.html index.htm;
location / {
#change this to a 404 img file .jpg
try_files $uri $uri/ /notfound.jpg;
rewrite "/s([A-Za-z0-9.]+)?" /small/$1 break;
rewrite "/o([A-Za-z0-9.]+)?" /orig/$1 break;
rewrite "/([A-Za-z0-9.]+)?" /medium/$1 break;
}
location = / {
rewrite ^ http://domain.com permanent;
}
}
The third rewrite is the one I'm looking to replace with my non static served image file, any idea how to go about this?

Update 2:
Ok, so the actual files are in /images/size/image.jpg and not actually /m/, /m/ is just a psuedo directory.
Given that, I think it should be as simple as:
server {
server_name i.domain.com;
access_log /var/log/nginx/i.domain.com.access.log;
error_log /var/log/nginx/i.domain.com.error.log;
root /var/www/domain.com/html/images;
location / {
rewrite /s([A-Za-z0-9.]+)? /small/$1 break;
rewrite /o([A-Za-z0-9.]+)? /orig/$1 break;
rewrite /([A-Za-z0-9.]+)? /medium/$1 break;
#change this to a 404 img file .jpg
try_files $uri $uri/ /notfound.jpg;
}
location = / {
rewrite ^ http://domain.com permanent;
}
}
But not 100% sure on it. Give that a shot and see. I moved the try below, as it was trying the files, which did not exist, first and then erroring out.
UPDATE
Since you are trying to just pass it through to a script, we need to capture that and pass it through to the script. I changed the root, since you are doing a "psuedo" images directory and we will need access to the image processing script.
Ok, since there is no PHP script in the middle (mis-read on my part) then the below should do what you want it to.
#setup subdomain i.domain.com
server {
server_name i.domain.com;
access_log /var/log/nginx/i.domain.com.access.log;
error_log /var/log/nginx/i.domain.com.error.log;
root /var/www/domain.com/html;
location ~* \.jpg { # add more extensions if you need to
#change this to a 404 img file .jpg
try_files $uri $uri/ /m/$uri /m/notfound.jpg;
#get the main part working first
#rewrite "/s([A-Za-z0-9.]+)?" /small/$1 break;
#rewrite "/o([A-Za-z0-9.]+)?" /orig/$1 break;
#rewrite "/([A-Za-z0-9.]+)?" /medium/$1 break;
}
location = / {
rewrite ^ http://domain.com permanent;
}
}
If that works, I am not sure how to go about doing the rewrites for the small / orig / medium (as I am not sure about the logic needed), but hopefully you can get it working.
In your domain conf, you just need to add a location for /m
location /m {
rewrite ^/m/(.*)$ http://i.domain.com/$1 permanent;
}
Should do it, pending any minor mistakes.
