Combine multiple images into 1 PDF with Mac

Kinda random title, right? But hell, I needed it and I received no questions from you, so why not share this amazing way of merging images into one PDF. On the HP help page there is a thread called Scanning multiple pages into 1 PDF with Snow Leopard & HP C3180. If you scroll down a bit to the entry added by Blue_Melnick on 08-31-2009 07:47 PM you will see how easy it is. It actually made me want to use Automator more :)
