Image tag in XML View

Hi everyone:

I have this in my XML View.

<content>

<Image src="localhost:8080/webapp02/images/01.jpg"/>

</content>

But the picture cannot be displayed.

I have opened this url directly in the browser and I can see the picture.

Moreover, I have also tried  <Image src="http://www.sap.com/global/ui/images/global/sap-logo.png"/> and it works well.

I am wondering who knows this. BTW, my picture is a little bigger than the picture of sap-logo .
