good way to batch rename files?

[Turian.Spectre]

I need an app that can batch rename files. I want one that will take all my files and remove certain words out of the name.

for example:
pictures-dog.png
pictures-cat.png
pictures-mouse.png

I would like the result to be:
dog.png
cat.png
mouse.png

any suggestions?

Automator is perfect for this. or try A Better Finder Rename

a better finder rename works great. not hard to figure out either thank you.
