I have make a load of images and get them special effects and I use IDE Eclipse, when I compile in the IDE, CTRL + F11, load my program, the issue is when I create the jar file, because it´s seems not execute the program. I put the images in the directory: C:\Users\Fernando\workspace\KillerGame\bin\capitulo6 and inside this dir there´s a txt file, which I use to load differents types of image and I use the method to load this archive txt getResourceAsStream(capitulo6/imsInfo.txt), and I thought this error is about this method or the images is in the wrong directory inside of jar, this is the class to load the images:
public class ImagesLoader

private final static String IMAGE_DIR = "/capitulo6/";

is an ArrayList of BufferedImages */

> this is the class to load the images:
don't need to read all the fluff, create a small app to load just a single image.
if it also has the same problem, post that code, using code tags.
note: file names in jars are case sensitive, many ide's compensate.
