If ImageMagick is not compiled in, or when enabled with the `-R` option, the images
are not modified, and are transmitted as-is. Use this if you can guarantee that
the generated files are smaller than 50kB and not larger than 320x240 pixels.
+Files whose name end in `_PadEncRawMode.png` or `_PadEncRawMode.jpg` will always
+be transmitted in RAW mode.
It may be useful to apply [`optipng`](http://optipng.sourceforge.net) to any PNG file prior to transmission.
