7on said:If I need to edit a photo in Photoshop for instance, I drag the photo from iPhoto to the Desktop. I edit and save to the desktop and redrag back into iPhoto and delete the original.
There's a simpler way:
In iPhoto preferences you can select "On double-click: Opens in other" and then select Photoshop. That way, when you double-click a photo in iPhoto, it opens it in photoshop automatically for editing. That should save you a few steps.
