Many APRS newcomers don't realize that you don't actually transmit
little pictures or bitmaps over the air. You only send a two-character
alpha-numeric control code over the air, that causes existing images
stored in the program at the other end to be selected and displayed.
Details on the APRS symbol set and how they are encoded are here:
<http://wa8lmf.net/APRS/APRS_symbols.htm>
Most APRS software can't be readily updated with new symbols. The only
ones that can be easily updated are UIview, APRSplus (which is now
essentially an orphan due to a dependency on an obsolete version of
Street Atlas) and and the Linux-based Xastir. Not to mention the
symbol sets at findu, APRSfi, OpenAPRS and other web sites -- and the
symbol sets embedded in the firmware of Kenwood radios, mapping GPSs and
other hardware devices.
Until you get EVERYONE to update their software (and with some programs
this is impossible), you can't be confident what the other person will
see (or if they will even see anything at all) -- if you use introduce
and use new symbols.
Bottom line -- It's nearly hopeless.
