I just thought I'd share my knowledge... For anybody wanting to make triggers out of your automator workflows
(I have one that rotates the selected images right / left, one that zips the selected files etc.) There's one thing that needs to be changed to get your workflows to work with a trigger. You need to open your workflow in automator, and add 'get selected finder items' to the top of your workflow. Once that's done, everything will work fine :)
