Automatic Image Resize/Crop Configuration (Nginx)

Here are practical examples:

location /thumb {
    alias /var/www/html/public/resize;
    set $width 0;
    set $height 0;
    set $dimens "";
    if ($uri ~* "^/thumb_x(\d*)x(\d*)/(.*)" ) {
        set $width $1;
        set $height $2;
        set $image_path $3;
        set $demins "_$1x$2";
        set $image_uri image_resize/$image_path?width=$width&height=$height;
    }
    if ($uri ~* "^/thumb_xx(\d*)/(.*)" ) {
        set $width 10000;
        set $height $1;
        set $image_path $2;
        set $demins "_xx$1";
        set $image_uri image_resize/$image_path?width=$width&height=$height;
    }
    if ($uri ~* "^/thumb_x(\d*)x/(.*)" ) {
        set $width $1;
        set $height 10000;
        set $image_path $2;
        set $demins "_$1xx";
        set $image_uri image_rs/$image_path?width=$width&height=$height;
    }
    if (!-f $request_filename) {
        proxy_pass http://127.0.0.1/$image_uri;
        break;
    }
    proxy_store /var/cache/nginx/pressify/resize$demins/$image_path;
    proxy_store_access user:rw group:rw all:r;
    proxy_set_header Host $host;
    allow all;
}

location /image_resize {
    alias /var/www/html/public/;
    image_filter crop $arg_width $arg_height;
    image_filter_buffer 5M;
    image_filter_jpeg_quality 95;
    allow all;
}

location /image_rs {
    alias /var/www/html/public/;
    image_filter resize $arg_width $arg_height;
    image_filter_buffer 10M;
    image_filter_jpeg_quality 100;
    allow all;
    expires 2d;
    add_header Cache-Control public;
}

Access thumbnails via URLs such as /thumb_x300x200/image.jpg for cropping or /thumb_xx200/image.jpg for resizing.
