+About PNGs
+
+   PNG is the Portable Network Graphic format. It is an open standard, not
+   burdened by patents (like GIFs). It is a highly compressed format (though
+   not "lossy" like JPEGs - lossiness allows files to be much smaller, but
+   introduces 'mistakes' in the image when saved), and supports 24-bit color
+   (16.7 million colors) as well as a full "alpha channel" - that is, each
+   pixel can have a varying degree of transparency.
+
+   For more information, visit: http://www.libpng.org/
+
+   These features (openness, losslessness, compression, transparency/alpha)
+   make it the best choice for Tux Paint. (Tux Paint's support for the PNG
+   format comes from the Open Source SDL_Image library, which in turn gets it
+   from the libPNG library.)
+
+   Support for many colors allows photo-quality "rubber stamp" images to be
+   used in Tux Paint, and alpha transparency allows for high-quality brushes.
+
+How To Make PNGs
+
+   The following is a very brief list of ways to create PNGs or convert
+   existing images into PNGs.
+
+  GIMP & Krita
+
+   Excellent tools with which to create PNG images for use in Tux Paint are
+   GIMP and Krita, both high-quality Open Source interactive drawing and
+   photo editing programs.
+
+   It is likely that one or both are already installed on your system. If
+   not, they should be readily available from your Linux distribution's
+   software repository. If not, or to learn more, visit http://www.gimp.org/
+   and http://www.krita.org/, respectively.
+
+  Command-line Tools
+
+    NetPBM
+
+   The Portable Bitmap tools (collectively known as "NetPBM") is a collection
+   of Open Source command-line tools which convert to and from various
+   formats, including GIF, TIFF, BMP, PNG, and many more.
+
+   It is possible that it's already installed on your system. If not, they it
+   be readily available from your Linux distribution's software repository.
+   If not, or to learn more, visit http://netpbm.sourceforge.net/.
+
+    cjpeg/djpeg
+
+   The "cjpeg" and "djpeg" command-line programs convert between the NetPBM
+   Portable Any Map (PNM) format and JPEGs. It is possible that it's already
+   installed on your system. If not, they it be readily available from your
+   Linux distribution's software repository. If not, or to learn more, visit
+   https://jpegclub.org/.
