Hot Simple Image Viewer is keyboard and mouse controlled viewer intended to make viewing of files inside one folder easy.

Inspired by good ol' Irfan view it uses simply shortcuts:

- space to move to next file in directory;
- enter to toggles full screen view;
- arrow keys to navigate back and forth.
- cmd+o to open another folder
- cmd+i to show file information

- cmd+enter to start a slideshow
- cmd+c to stop slideshow

This way you can open any folder and click through every photo/image in this folder. This app is specially designed for easy to use batch image viewing.

It's perfect for showing photos to your grandmother!
