Hi Andi,
I think the main feature looking for here is to:
- upload a custom image file to use as the base map
- Drop pins on the map to indicate locations (bonus: have the pins be customizable image files)
- have the pins be linkable to wiki pages
Imagemapping will do 1 and 3.
the openlayer pluggins look to be able to do 2 and maybe 3, but I think not 1.
any option for all three?
