Neon is a simple image viewer. It's designed to be lightweight, fast, and easy to use. It's written in Python/EFL. The Project is hosted on OpenmokoProjects.


  • Fast and finger friendly.
  • Zoom (in, out, fit to window) and rotate.
  • Slideshow.
  • Full screen viewing.
  • Minimal EXIF support.
  • Window auto-rotation via accelerometers data.

Download and installation

You can install Neon directly from Web with opkg. All packages are available here. For example:

opkg install

If your system uses Python 2.6 (not 2.5) like SHR or FSO, you must install an alternative package:

opkg install

Neon is in SHR feeds already, so to install neon on SHR, simply type:

opkg install om-neon

Usage: neon [options] [path]

  --version             show program's version number and exit
  -h, --help            show this help message and exit
  -e ENGINE, --engine=ENGINE
                        which display engine to use (x11, x11-16), default=x11-16
  -f, --fullscreen      start in fullscreen mode
  -r 0/1, --auto-rotate=0/1
                        auto rotate images by dimensions, default=1
  -R 0/1, --auto-accel-rotate=0/1
                        auto rotate window using accelerometers, default=0
                        delay for slideshow [sec], default=4
  -t THEME, --theme=THEME
                        which theme to use (default, b_and_w), default=default
  -d DELAY, --bars-disappear-delay=DELAY
                        auto-hide delay for navbar and toolbar [sec], default=0

To customize launch options, you can edit /usr/share/applications/neon.desktop file.

For example, to use "Black & White" theme and enable window auto-rotation via accelerometer data, modify the "Exec" line like this:

Exec=/usr/bin/neon -R 1 -t b_and_w
