Quick File Renamer
"I'm a graphic designer that works on tons of images in Photoshop. I have a script that saves all of the layers of files out of Photoshop as jpegs and then tiffs. After this is done, I use Quickrenamer to do the renaming of the files. It works as described and has enough versitility to help me get my work done quickly."
