A very good and free simple image viewer software…
RoboReader is a image viewer program and its free. When it comes to file formats, it is not the strongest, because the program is limited to the main formats (.jpg, .bmp, .png, .gif, .tiff and .ico).
You can also browse for images content in different types of archive files (ZIP, RAR, 7Z, CBZ, CBR).
When you double-clicked on a picture to see it, can RoboReader browse through all the other images in the folder or archive file, either automatically (thrue a slide show) or manually (using the left and right arrow keys to move through the list).
There are lots of keyboard shortcuts to manipulate the image you are watching.
The program is only available for Windows users, and can only be used by Vista-users and upwards
