title: Automator/Applescript rename files if
body: <p>I have a large list of images that have been misnamed by my artist. I was hoping to avoid giving him more work by using Automator but I'm new to it. Right now they're named in order what001a and what002a but that should be what001a and what001b. So basically odd numbered are A and even numbered at B. So i need a script that changes the even numbered to B images and renumbers them all to the proper sequential numbering. How would I go about writing that script?</p>
