[Viking-devel] Using local maps: how?

All,

Not really a devel question but the website said to email this list so here it 
is.

I have been using viking for a while, so far using openstreetmap maps.  This 
was great to edit GPS tracks and upload them to OSM for more data input.

I am now trying to use my own maps.  I have a collection of maps saved as png 
files (could convert to something else but I notice that viking uses png) and I 
would like to use them in a layer.  Apparently, the map layer will only 
download maps from a server.  However, the downloaded maps are saved locally 
so it must be possible to put my maps somewhere for viking to find them.

However, I don't understand how the georeferencing is done, nor how the naming 
is done.  I have googled and looked through documentation, but didn't find the 
answer.  Anybody can point me in the right direction?

Cheers,

Fred
