Hello Igor S.,
Thank you for your help.

You suggestion is great, but my problem is a little bit complicated.

The image name is flexible, can be from 0.jpg to 23456.jpg, we organize
the image files into folders, whose name is the number divide by 1000.
For example, the folder 100 saves the file 100000.jpg to 100999.jpg.

Both the folder and file name are flexible in my case.

Do you have any suggestion on it?

Thanks,
Yanxin

location /img/ {

location ~ ^/img/(\d)(\.jpg)$ {
    alias   /path/to/img/0$1/$1$2;
}

location ~ ^/img/(\d\d)(\d*\.jpg)$ {
    alias   /path/to/img/$1/$1$2;
}

return 404;

}

As far as I understand original question, the following should
work (same as above, but fixed to use division by 1000 instead of
two first digits):

location /img/ {

location ~ ^/img/(\d+)(\d\d\d\.jpg)$ {
    alias /path/to/img/$1/$1$2;
}

location ~ ^/img/(\d+\.jpg)$ {
    alias /path/to/img/0/$1;
}

return 404;

}
