Before I start writing an AppleScript to do this I was wondering if anyone knew of any way to rename photos in Sequential Alphabetical Order. Let me give you an example. For one of the papers I do some freelance shooting for I need to attach a job ID that has my initials, job number and then a letter that uniquely IDs the photo. So for my third Job I would need to submit photos named RQ003A, RQ003B, RQ003C etc. Generally the number of photos will never exceed the length of the alphabet (Although if it did I would assume it would either have to go to AA, AB etc. or ZA, ZB etc.). Does anyone have any ideas. I've tagged this with 'Lightroom' as I've just started a trial of Lightroom and quite like it so far, but I am open to other renaming applications. I should also point out I use a Mac.
