What is the best image viewer for OS X that performs like the Windows built-in image viewer, so that one can go through images using the arrow keys or display a slide show?
OS X doesn't have this functionality built in, but here are a couple of ways to get similar functionality:Method 1: Use Finder's preview windowOpen the preview window: CMD+SHIFT+PThis allows you to view the images on the right side of the Finder window.Caveat: The images are not fullscreenMethod 2: Open all images in the directory in Preview1. Enter "kind:jpeg" in the top right search box2. Make sure "Search: [Directory]" is selected, not "Search: This mac"3. Enter CMD+A to select all images4. Double-click on any image to open all selected images in Preview5. In Preview, you can use the arrow buttons to navigateCaveats: The procedure requires a lot of clicks and you start previewing the first image in the directory, not the picture you double-clickMethod 3 (recommended): Use a 3rd party replacement for PreviewBecause I find Preview quite lacking, I prefer a 3rd party application. I'm sure there are plenty to choose between, but I can recommend Xee.To set Xee as default application for JPEG images:1. Right click a JPEG image2. Select "Get Info"3. Open "Open with:"4. Select Xee in dropdown menu5. Click on "Change All..." to set Xee as default application for all JPEG image filesIf you regularly view other image file types, repeat the process for each type, like GIF, PNG, TIFF, etc.Then you can simply double-click an image and start browsing the images in the folder.When you have found the image you were looking for, you can open the File menu in Xee to either "Reveal in Finder", "Open in Editor" or "Share" to keep working on it.Method 4: Don't use Finder at all to organize imagesThis seems to be the proper OS X way of working with images. Use Apple Photos, Adobe Lightroom or another application to organize your images, and don't use Finder at all.Coming from Windows and being used to organize images in folders by date, this method is pretty foreign to me. However, if you use iCloud to backup your images, it makes sense to use Apple Photos. I'm using Dropbox and Google Drive to backup images, so I haven't really been able to test this method properly.
