+Para que funcione, debes descargar el contenido de `/var/www/html/images` de rarceresearch.fun a tu compu.
+Puedes usar el siguiente comando desde tu compu en linux:
+
+```
+rsync -avzh root@rarceresearch.fun:/var/www/html/images /tmp
+```
+
+Eso syncroniza un directorio local de tu compu (`/tmp/images`) con el directorio `/var/www/html/images`  de rarceresarch.fun
+
+Luego puedes correr el programa de python localmente usando:
+
+```
+python tp-smart-process.py /tmp/images 4000
+```
