Missed Image Viewer

Missed Image Viewer is free, fast, lightweight image viewer for Mac.

Open a single photo from Finder and the app automatically scans the current folder, so you can move through nearby images without manually selecting a whole batch of files first.

It is designed for the simple workflow many people miss: double-click an image, view it immediately, then use the keyboard to browse the folder in order.

Main features:
• Free forever! 
• Open one image and browse the entire folder
• Navigate with arrow keys and keyboard shortcuts
• Full-screen viewing
• Zoom and pan
• Rotate images
• Move images to Trash
• Supports JPEG, PNG, BMP, TIFF, and GIF files
• Works locally with your files

Missed Image Viewer does not try to organize, sync, edit, or manage your photo library. It focuses on one thing: quickly viewing images in folders.
