As in the case of the absence of a file on the server, redirect the request to PHP

For example, I have the URL /images/articles/200x200/1.jpg I want nginx to give this picture and all the pictures from the images folder with statics, and if there is no file on the server, I would process the same URL via php

I think here is something like that, but you need to finish it probably:

location /images { location ~ ^/images/uploads/ { error_page 404 .... $uri @fallback; } }
