Nomacs is one of the free photo viewers that supports many platforms like Windows, Mac and Linux systems. Apart from that, on-the-fly image processing is provided for sharpness, rotation, colour balance, contrast, and local under-/overexposure. JPEGView’s GUI is very minimal and, in terms of looks, it’s pretty average compared to other photo viewers.
JPEGView is a very configurable photo viewer/editor for JPEG, BMP, WEBP, TGA, PNG, GIF, and TIFF images.
