"excellent fast editor"
It brings up images fast and makes it easy to move from one image to another in the same folder, as well as enlarge, rotate, brighten, darken. Also easy to change image format (tif to jpg, etc.)
Displays actual files in a folder, but ignores links to images in other folders. Usually I'd like to see all the images stored in a folder and the ones with shortcuts in that folder.
Fast and easy to work with.
