Sprite_Cache.getImage("tile_grass_01");
It returns the image stored under the SpriteCacheKey (Sck). It holds images for tiles, actors and verts... The preview is small right now, but I'm working on magnification :)
Eventually I'll replace the 'Filename of Graphic' text box with a dialog that allows you to copy the image from somewhere on your hard drive... but right now, that is not needed.
