Remove Characters in Filename

[Wayne_Wickson]

In many of the filenames I have to change, there is a three-digit page number just before the ".jpg". The examples below show this. How would I remove just the page numbers leaving the rest of the filename intact, including the .jpg extension?

Thanks.

With a checkmark for "Inc.Ext." the "Match" and "Replace" can be like...
(.+) \d{3}\.(?i)jpg$
\1

If needing something more exact, can change the "Match" to...
(.+ 20\d\d_\d\d_\d\d) \d{3}\.(?i)jpg$

Thanks, Luuk. The first example works like a charm! Is there a good tutorial showing how to use the many combinations of this excellent software?
