I upgraded from Windows 7 to Windows 10 recently.
To my amazement there is no simple way to view pictures, except for Paint/Paint3D, which I really hate.
Thats why I threw together, whith help from C# and .Net Framework 4.0, my own SimpleImageViewer. Just set it as your default Imageviewer and it should work[1].

Supported file types:

  • .png
  • .jpg/jpeg
  • .gif (animated/working)
  • .tiff
  • .bmp

If you find more supported files, let me know.

If you want to try it you can grab it here: SimpleImageViewer
