Yes, the original concept of the APRN was a local piece of
software (think Igate) that monitored a local area channel
(channels) and collected all SSTV live images with APRS tags on
them for labeling and retrieval.  Then the images were available
on the WEB locally from that server via a unique URL.  But also
like an Igate, this APRN node forwards that packet LABEL along
with the URL into a central global APRN server.

So the images are kept locally for local access (Via RF or local
WEB) but the links and pointers to those images are contained in
a single packet that is available globally.

Come to think about it, that one packet per image would not be
an unnecessary burden on the existing APRS global network.  SO
although I initinally was thinking about a separate APRN
distribution system, now I think that with just one packet per
image, that we shoud consider it on the APRS network.

Since each image was accepted and filed at the local APRN node
with its "APRS" tag, then the images can be retrieved locally
by:
1) By callsign
2) By area (by location)
3) by orientation (view west, etc)
4) by subject (fire, flood, power line, etc...)

Since the URL was distributed in the same packet.

Next email will address format of that one packet:
