Batch File Renamer is an advanced windows software which allows you to rename files and folders which suits even very complex needs. Since it works with all the types of files you now need not to find explicitly for images ( which we talked about it here ).  It works on WIndows XP and Vista Both.

Another addon you get is , you can just right click a folder and say Batch Rename i.e the menu is integrated with windows which lets you select any folder and do the job. You can also rename files with invalid file name characters for which the characters can be setup in the configuration file.
