I'm looking for a good little JPG viewer, sort of like ACDSee but smaller and preferably cheaper. I use FastStone on Windows, which is great as it's super quick, has plenty of thumbnail options, and will scale up or down images in full screen mode very cleanly. I've tried Phoenix Slides on the Mac but it's a bit clunky. Can anyone recommend anything? Ideally something which I can throw any random folder of images at and it will without fuss generate thumbnails and let me browse flick through the images in full screen mode. Thanks!
