Create Smart Folders and sort by date, type, location, etc... Whatever you want. Then open the folder. You can tell Finder to use View as Gallery in those folders.
You can also just continue to use Grid view and tell Finder to use large preview icons in that folder.
Not that easy depending on the number of pictures and the folder content.
> Use the arrow keys to move between the different files.
Won't work correctly in grid view.
Also: I don't want to mess with the way I set up Finder to display/sort the folder just to view the pictures.
