File rename/delete program needed

[Binh]

Okay, let's say I have a LOT of files, each with it's own name, bit each file has the word "binh" in front of it, is there any program that can go through automatically and delete just the text "Binh" and leave the rest alone?

For example: My files are:

binh rock.jpg
binh water.jpg
binh river.jpg
binh bird.jpg

And I want:

rock.jpg
water.jpg
river.jpg
bird.jpg

Without going through each one, because there are a lot of files. Help please!
