Alright here it is, my first REAL map contribution
<ImageStyle Name="exp15_dun_plane_of_justice" displayname="Plane of Justice: Eternal Prisons" zonerect="-53, -55, 52, 36">
<ImageFrame Source="images/maps/map_exp15_dun_plane_of_justice.dds" SourceRect="0,0,508,436" />
The .dds for in-game and .jpg for website are attached below, as well as a picture to see what the zone looks like. I tested it and apart from moving the southern wall a smidge to far it works perfecly (and I can't be arsed to fix that lol :P).
Do you need anything else to make this work?
Yeah you need to move Planes of Justice: Eternal Prisons to Chaos Descending, it was so late last night that I posted it in the Planes of Prophecy thread by accident rather than here, sorry for making you do extra work *sigh*.
There are also more new zones to add in post #4.
