And here is the (even worse) map for Echo Caverns!
So same as above, get the .dds file, dump it in maps.
Grab code below and add it to the file "_User_MapStyles.xml"
Code:
<ImageStyle Name="exp17_rgn_echo_caverns" displayname="Echo Caverns" menugroup="Blood of luclin" zonerect="-1096, -936, 668, 1106" >
<ImageFrame Source="images/maps/map_exp17_rgn_echo_caverns.dds" SourceRect="0,0,436,506" />
</ImageStyle>
