Is there anyway to do this? Merge two .jpg's with automator or something? I have a lot of photos manipulated with automator and would like to add a step to add my watermark, but don't know how to do it.
Nevermind, I found an Aperture feature that will let me create my own 'export versions' that can contain a watermark. The placement options are a bit annoying, but it will work fine.
