Wouldnt a JAR file be better?
1. Make a manifest.txt file containing the following line.
Main-Class: YourClassNameHere
2. Try running the jar command with the following code, inserting your files.
jar cvmf manifest.txt TheNameForJar.jar YourClassFile.class PICSorStuff.*
Try that. You should just have to double click on the JAR file to run it.
