More fun stuff, played with Automator recently because I wanted to find a quick way to set image tags for multiple images. You can do it manually in Preview.app, but wanted a drag and drop solution. I guess I got inspired after watching a recent ScreenCastsOnline podcast (http://screencastonline.com/); as a demo, they showed building a workflow for scaling images by 50%. After a bit of searching, I found an Write IPCT Tags action on automator.us (http://automator.us/leopard/downloads/index.html)
With that action, can create static workflow, or can prompt for all the tags to set.
