Is there a way to just right click on an image file and then have the option to set the picture as a desktop background (like in Windows). I find it rather annoying that I have to drag a photo to the little monitor to change the background. Also all my pictures are in many organized folders so I don't want to add all the folders to the desktop background options under System Preferences. Even under Preview I can't find an option to set a picture as the background. Also is there a free (or reasonably priced application) that is a good and quick image viewer/editor that will also let me see all the pictures in that directory automatically (kind of like Windows again) by just pressing "next" or the arrow keys. I can't seem to do that under Preview unless I drag the whole folder. I just want to be able to click on 1 photo and then be able to navigate to the others from there. Thank you for your help!!
