I copied the map image from a screenshot of the built-in map. The zonerect was a pain to figure out, but it works. Just in time for the holiday to be over
Code:
<ImageStyle Name="live_tinkerfest_innovation_01" displayname="Innovation: Tinkerer's Trial [Heroic]" zonerect="-437, -400, 405, 240">
<ImageFrame Source="images/maps/map_exp14_dun_plane_of_innovation_0.dds" SourceRect="0,0,800,600" />
</ImageStyle>
<ImageStyle Name="live_tinkerfest_innovation_01_solo" displayname="Innovation: Tinkerer's Trial [Solo]" zonerect="-437, -400, 405, 240">
<ImageFrame Source="images/maps/map_exp14_dun_plane_of_innovation_0.dds" SourceRect="0,0,800,600" />
</ImageStyle>
