Unable to access Images inside executable jar

I am using Eclipse IDE for development .

I am trying to make a executable jar and give it to others so that they can run it in their machine.

I have followed the below documentation to access the image files inside the jar

( https://sikulix-2014.readthedocs.io/en/latest/scripting.html#image-search-path-where-sikulix-looks-for-image-files

String clazz = "testAPI.Test";
String imgFolder = "/imgs";
String img = "test.png";
 String inJarFolder = clazz + imgFolder;
ImagePath.add(inJarFolder)
)

With the above steps mentioned in the doc , the executable jar works fine and is able to access the image files inside the executable jar , when it is executed from my computer( the computer where the code was developed ) .

when the same jar is executed in a different machine , it doesn't work.

But the same code when run in eclipse IDE in a different machine works well and is able to identify images.

I want this jar to be working in other machines too . How can we resolve this ?
