I can't get the hello world example to work.

[GoogleCodeExporter]

What steps will reproduce the problem?
1.Run the Quick start code
2. Wait for the browser to open webpage
3.Exception in thread "main" org.sikuli.api.SikuliRuntimeException: Image file 
can not be loaded from http://code.google.com/images/code_logo.gif because 
Can't get input stream from URL!
    at org.sikuli.api.ImageTarget.<init>(ImageTarget.java:46)
    at HelloWorldExample.main(HelloWorldExample.java:25)

What is the expected output? What do you see instead?

Displaying "Hello World" next to the target and then clicking on it.

What version of the product are you using? On what operating system?
windows 7 32bit
jdk1.7.0_09
sikuli-api-1.0.2-standalone.jar

Please provide any additional information below.
I am using the following code

                Target imageTarget = new ImageTarget(imageURL);

                // Wait for the target to become visible on the screen for at most 5 seconds
                // Once the target is visible, it returns a screen region object corresponding
                // to the region occupied by this target
                ScreenRegion r = s.wait(imageTarget,5000);

                // Display "Hello World" next to the found target for 3 seconds
                Canvas canvas = new DesktopCanvas();
                System.out.println("r: " + r); 
                canvas.addLabel(r, "Hello World").display(5);

                // Click the center of the found target
                Mouse mouse = new DesktopMouse();
                mouse.click(r.getCenter());
        }
}

Might be because of image resolution difference between how the image actually 
looks and how the image is getting rendered on the browser. Have you tried with 
a different set of website and image? Or instead of the URL, you can try saving 
it in the project workspace and calling the constructor of ImageTarget with a 
new File object like:

Target imageTarget = new ImageTarget(new File("img/code_logo.gif"));

I encountered the same issue with you, but i run the program at my office, the 
PC connected the network via the Proxy server. So when I added the the proxy 
configuration to the program like below:

System.setProperty("http.proxyHost", "proxy server of you");  
System.setProperty("http.proxyPort", "8080"); 

Run the program, it can work normal
