In this case, pay attention that the renumber script does
not pay attention to not overwrite files. This can lead to
problems when adding files. Let's say you have

	pic_01.jpg
	pic_02.jpg
	pic_03.jpg

and add a file new.jpg, so you have

	new.jpg
	pic_01.jpg
	pic_02.jpg
	pic_03.jpg

If you now run

	renumber pic jpg

you'll have

	pic_01.jpg = new.jpg
	pic_02.jpg = pic_01.jpg
	pic_03.jpg = pic_02.jpg
	pic_04.jpg = pic_03.jpg

and the "source pics" will be "removed", so you end up with

	pic_04.jpg = neu.jpg

A workaround is to use the MC to prefix all files with an
arbitrary letter, and THEN run renumber, e. g. select all
(grey *), PF6, to "X*" (where "X" is the arbitrary letter)
and have

	Xnew.jpg
	Xpic_01.jpg
	Xpic_02.jpg
	Xpic_03.jpg

which can be processed with "renumber pic jpg" now without
any problems because the existing prefix isn't the same as
the renumbering prefix.

As you see: I have a reason to believe that I should better
write a new script that takes such things into mind and maybe
offer reverse renumbering, overwrite protection and a better
selection which files (instead of hardcoded *) to process.

It's worth it. The MC is a powerful and still easy to use
tool for file administration.
