+      nomacs is a free, open source image viewer, which supports multiple
+      platforms. You can use it for viewing all common image formats including
+      RAW and psd images.
+
+      nomacs features semi-transparent widgets that display additional
+      information such as thumbnails, metadata or histogram. It is able to
+      browse images in zip or MS Office files which can be extracted to a
+      directory. Metadata stored with the image can be displayed and you can add
+      notes to images. A thumbnail preview of the current folder is included as
+      well as a file explorer panel which allows switching between
+      folders. Within a directory you can apply a file filter, so that only
+      images are displayed whose filenames have a certain string or match a
+      regular expression. Activating the cache allows for instantly switching
+      between images.
