Web Friendly Renamer

Function: Renames files for websites; removes spaces, sets all lowercase.
Author: Automator World
Notes: Spaces in filenames are converted to dashes, and set to all lowercase (This is a File.jpg becomes this-is-a-file.jpg). I actually created this workflow as a Finder plug-in for processing workflows and actions submitted to AW, and it occurred to me others might find it useful as well. It works best as a Contextual Menu Plug-in: Copy into ~/Library/Workflows/Applications/Finder/
