[TriLUG] Open source way to wirelessly transfer pictures from dslr to computer

[Mauricio Tavares via TriLUG]

      I have seen some solutions that (a) are commercial (b) very
camera-specific (some Canons and Nikons) and (c) suck because I do not
want to upload to the cloud or run a certified insecure network
(windows 3.11 auth). I also know there are memory card with built-in
wifi, which is probably what those vendors do.

Suggestions?
