GH3, WiFi and Flickr
That is redundant.
What I have found out is that I can join Lumix Club, and apparently upload to Lumix Club which in turn will upload to a variety of on line sources, including Flickr.
But the whole setup process is not for the faint of heart, because there is very little documentation and what there is is obscure. For example, the only way (I think) of joining the Lumix Club is through your GH3. That is, you can't register online except only through the GH3. By trial and error I'm finding out how to proceed.
Maybe if I have it all figured out I will write up some instructions and post them.
