Description:

nomacs is a free image viewer for windows, linux and mac systems, which is licensed under the GNU Public License v3. nomacs is small, fast and able to handle the most common image formats. Additionally it is possible to synchronize multiple viewers. A synchronization of viewers running on the same computer or via LAN is possible. It allows to compare images and spot the differences (e.g. schemes of architects to show the progress).
