Free mass file renamer for Mac OSX

Renamer4Mac was a good option for a while for batch renaming but then it stopped being free.

A great free mass file renamer for the Mac is Name Mangler.

Great for batch renaming of files like photos, filenames of songs, episodes in a series, etc., basically anything that you have lots of and they have similar names. So if I wanted to organize the pictures from my NYC trip a bit more neatly, instead of having pictures named CIMG1002, CIMG1005 (because you deleted 2 in between), it's good to make my photo names relevant to each other and neater, so it'd look something like NYC001, NYC002 (or any format you choose). Nice and neat way to organize your files.

If you're OCD about the way things look and are organized on your computer, this could definitely save you some time (and money if you were looking at Renamer4Mac). It'd also make it a lot easier to find pictures, and avoid any problems of copying over some of your pictures because they have the same filenames, or getting your pictures jumbled up if they're in the same folder.

Only problem with this is I can't seem to figure out how to get the toolbar icon in my Finder windows like displayed in the third image on the site.
