In Loquiz you can add a drawing to a map.  It should be meant to be a thematic or somehow augmented map for the game area, so it is just one per game. However there is some really cool usages for this feature.

One is that you can hide information into the map. For example, lets assume your game takes place somewhere in London. So you might add  hand drawn schematics to New York. As it is so far away it only becomes visible when a user knowingly zooms into that region. So during the game you might just refer that within a question saying that a player should “Go to New York to get some additional insight into the game.”

Remember they can only access the map when the question is closed, so even a better idea would be to refer to it when the players` answers are correct in after answer comment.

There are other uses for the picture layer. In the comments below let us know how you use it.
