Thanks Mr. Noodle. If I can figure this out, then Hazel will be my next software purchase. So far, I have not found any other app that can do this for me.
Actually, I heard about Hazel over on the Adobe Photoshop Forum for Macintosh. The thread was discussing the problem of suddenly losing your extensive image edits after an application crash -- sometimes even occurring when you are actually trying to save your work. See below:

I use hazel ( http://www.macupdate.com/info.php/id/22694/hazel ) to auto backup and name versions of psd's i'm working on (if you set it up right you can have a folder full of versions just like the history pallet in photoshop, except they don't consume ram and won't be effected by a crash) the only time i've had photoshop destroy a file is a crash during save. I'm sure photoshop used to save files."One major cause of an application crash in Photoshop is a lack of RAM memory available during complex operations. As mentioned above, apparently using Hazel can also make it possible to reduce the history palette size, a major user of RAM memory. Any suggestions?
