For OruxMaps you need to rename the .jgw (world file) to .tfw (technicality) and then run them through the desktop program, where you can create zoom levels and such to prep them for the App on the phone. Then copy them into the correct folder and finally select it in the app. Using .kml files is the same; once in the proper folder Orux finds them and makes them available in the app.
