    pViewer

    pViewer

    pViewer, a small and fast image viewer. Because less is more.

    All image viewers i've ever seen have something on screen other than the image they're displaying. I didn't like that, so, pViewer was born. And that's why everything in pViewer is done with the right click menu and keyboard shortcuts. I also didn't want to use two different viewers for viewing images and for reading comics, and that's why pViewer have a Manga/Comic mode. This project is written in C#, and uses the .NET Framework 4, which you need to run the software: https://www.microsoft.com/en-us/download/details.aspx?id=17851 I strongly suggest to open and read the Keyboard Shortcuts/Help menu in the software before starting to use it. Or you can read the How-to here: https://sourceforge.net/p/picoviewer/wiki/How-to/ You can find the Changelog here: https://sourceforge.net/p/picoviewer/wiki/Changelog/ Here's a review by findmysoft: http://pviewer.findmysoft.com/
