Is there a freeware OS X image viewer program out there that's fast and also does basic file management (renaming, copying, moving, deleting)? Basic image editing (resizing and cropping) would also be nice but not essential. I'm a veteran PC user who recently got my first Mac. I'm accustomed to ACDSee for Windows on my PC, which let me do what I just described -- rename, copy, move, and delete images as I browsed through them -- with almost no delays. By contrast, I have been using the Finder and Preview to browse through my images, and it's a chore. Finder is quick and is great for file management, but its image thumbnails aren't big enough to be useful. Preview is gorgeous, but it doesn't allow me to do file management on the files I'm previewing, and it's slow to boot. Surely there's a better way that I have missed. Help?
