When I switched to macOS, I missed Irfanview from Windows. I wanted a Mac app to quickly go through images in a folder by hitting left and right arrow keys, and also be able to copy the images to paste in another folder or in a document.

Thinking about it, it seemed like a pretty simple app to make and a great opportunity to dip my toes in Swift and Swift UI, so I did!

• Simple and fast (mostly thanks to Swift UI)
• Navigate images in a folder by hitting left/right arrow
• Copy image as...
  • ...an image (⌘C): Useful for pasting in a Finder window or into a Document
  • ...a file path (⌥⌘C): useful for pasting into a Terminal window
• Can show some basic information (filename, resolution, filesize) about image
• Trash (⌫) or Delete (⌥⌘⌫) files
• Multiple ways to open images:
  • Drag n drop into window
  • Drag n drop onto icon
  • File > Open... menu
  • Right click image > Open With
  • Command line: open -a /Applications/imageviewer5.app /path/to/image.jpg

• Download from the Releases page
• Minimum macOS version is 11.0
• Because I am not a registered developer your Mac will probably scream at you when you try to open it
  • Feel free to compile/build it yourself to avoid this

See the Issues page. Most annoying issue right now is probably that GIF images are displayed, but not animated (#5).
