How I use it, by example:

 1. Open directory in Dired:

        drw-r--r-- 1  40K Sep 13 22:08 .
        drw-r--r-- 1  24K Sep 13 22:08 ..
        -rw-r--r-- 1    5 Sep 13 09:37 0.jpg
        -rw-r--r-- 1    5 Sep 13 09:37 1.jpg
        -rw-r--r-- 1  282 Jun 20  2020 desktop.ini
        -rw-r--r-- 1 625K Sep 13 22:00 IMG_20210913_0001.jpg
        -rw-r--r-- 1 385K Sep 13 22:01 IMG_20210913_0002.jpg
        -rw-r--r-- 1 1.1M Sep 13 22:02 IMG_20210913_0003.jpg

 2. M-x wdired-change-to-wdired-mode

 3. M-x query-replace-regexp

        [^ ]+jpg → \,(1+ \#).jpg

    Result:

        drw-r--r-- 1  40K Sep 13 22:08 .
        drw-r--r-- 1  24K Sep 13 22:08 ..
        -rw-r--r-- 1    5 Sep 13 09:37 1.jpg
        -rw-r--r-- 1    5 Sep 13 09:37 2.jpg
        -rw-r--r-- 1  282 Jun 20  2020 desktop.ini
        -rw-r--r-- 1 625K Sep 13 22:00 3.jpg
        -rw-r--r-- 1 385K Sep 13 22:01 4.jpg
        -rw-r--r-- 1 1.1M Sep 13 22:02 5.jpg
