Question: I have these rewrite rules (I tried both with no avail):

```
location ~* "^/([a-z0-9]{32})\.png$" {
  rewrite ^ /index.php?page=log&id=$1 last;
} 

```

and

```
location ~* "/(?<hash>[a-z0-9]{32})\.png" {
  rewrite ^ /index.php?page=log&id=$hash;
}

```

and

```
location / {
  try_files $uri $uri/ @rewrites;
}

location @rewrites {
  rewrite "^/([a-zA-Z0-9]{32})\.png$" /index.php?page=log&id=$1 last;
  #...
}

```

Basically, I want the URL `http://example.com/aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa.png` to actually pass the parameters to my `index.php` script, and in the script, I got:

```php
$db->save_hash($_GET['id']);
header('Content-type: image/png');
readfile('images/beacon.png');
break;

```

But nginx is giving me a "not found", but other rewrites work fine. What gives?

Answer: 
this one worked for me:

```
    location / { 
    rewrite "/([a-z0-9]{32})\.png" /index.php?page=log&id=$1 break;
    }

```

Or if you want separeted location:

```
location ~* "/([a-z0-9]{32})\.png" {
rewrite /(.*) /index.php?page=log&id=$1 last;
}

```
Mark pointed out so I started removing all the included files, and boiled down to:

`/etc/nginx/conf.d/h5bp.conf`

that contains

```
# Basic h5bp rules

include /etc/nginx/conf.d/expires.conf;
include /etc/nginx/conf.d/x-ua-compatible.conf;
include /etc/nginx/conf.d/protect-system-files.conf;

```

the `expires.conf` got

```
# Expire rules for static content

# No default expire rule. This config mirrors that of apache as outlined in the
# html5-boilerplate .htaccess file. However, nginx applies rules by location,
# the apache rules are defined by type. A concequence of this difference is that
# if you use no file extension in the url and serve html, with apache you get an
# expire time of 0s, with nginx you'd get an expire header of one month in the
# future (if the default expire rule is 1 month). Therefore, do not use a
# default expire rule with nginx unless your site is completely static

# cache.appcache, your document html and data
location ~* \.(?:manifest|appcache|html|xml|json)$ {
  expires -1;
  access_log /var/log/nginx/static.log;
}

# Feed
location ~* \.(?:rss|atom)$ {
  expires 1h;
  add_header Cache-Control "public";
}

# Favicon
location ~* \.ico$ {
  expires 1w;
  access_log off;
  add_header Cache-Control "public";
}

# Media: images, video, audio, HTC
location ~* \.(?:jpg|jpeg|gif|png|ico|gz|svg|svgz|mp4|ogg|ogv|webm)$ {
  expires 1M;
  access_log off;
  add_header Cache-Control "public";
}

# CSS and Javascript
location ~* \.(?:css|js)$ {
  expires 1y;
  access_log off;
  add_header Cache-Control "public";
}

# WebFonts
# If you are NOT using cross-domain-fonts.conf, uncomment the following directive
location ~* \.(ttf|ttc|otf|eot|woff|font.css)$ {
  expires 1M;
  access_log off;
  add_header Cache-Control "public";
}

```

commenting that `expires.conf`, then it starts working, how can I fix this?
