For some apps this makes no difference, but in Preview for example, this means that a new window is created for each image, instead of a single window with a thumbnails drawer as you get when you open multiple images from Finder.
Another case is Quicksilver. When I drag multiple files onto Quicksilver in the dock, it puts all of them in the Quicksilver pane (screenshot below). (This even works from GraphicConverter.) But if I use the "Edit With" menu, the Quicksilver pane activates and deactivates rapidly and only the last item is selected. I would prefer to use the Edit With menu because then I could bind a keyboard shortcut to it and not have to move the cursor.
Basically, if you could make it work the same way as the Terminal command
Code: Select all
open -a Quicksilver 1.jpg 2.jpg ...
