How can I rotate my images directly from the finder? I would like to rotate my images directly from the Finder. 

The best would be one of these:


a button to click in the menu bar of every Finder's window
a button to click in Quicklook


But, if it can be done with a keyboard-shorcut, it would be fine also.

Is one of these features possible? And if yes, how can I do?
Yes - you can use Automator to make a service for Finder (or all applications) to perform rotation of images. Then you can assign a keyboard shortcut to that action.



I'm not aware of quicklook plug-in that rotate, but that's something that might exist. Modifying finder's shortcut bar might be the least likely way to activate things, but hopefully an Automator service (or app / droplet) will do.
