imgViewOn is meant to be your default operating system image file viewer and will open the major image file types (jpeg, png, gif, bmp and several others.) It will quickly display the image file without a border or top menu bar.
After installation set your image files assocations to open with imgViewOn. When an image is opened using imgViewOn you can edit the window/image size with the bottom, right, and bottom-right sides of the window.
