How to import art to the map as a loading screen HELP

There seems to be very nice art pictures in the art section, but they are .jpg and when I import them to the World Editor and try to use them as a loading screen or campaign screen, they don't appear in the list.

Should they be converted to .tga and how or what do I need to do? If it requires some tools please give me a link where I could get the tool for free.

loading screen: http://world-editor-tutorials.thehelper.net/loadscreen.php

preview screen: http://world-editor-tutorials.thehelper.net/minimap.php

+It's very simple and tools are free, good luck !

Thank you, vnakira!

I'll give it a try.
