Try putting that image in your portlet. Like if that is in your-portlet/images/arr.png then use
<img src="<%=request.getContextPath()%>/images/arr.png">

You cannot use fixed paths to images, all images must be relative to the web application.

That is a basic web server development thing which you should already be aware of to undertake web development.

You cannot. It's an application server thing, not just something you can override. It is there to ensure that you do not serve up resources outside of the application container, which would be a potential security leak.

As I previously mentioned and David also explaining, image should be in your document root. If you are not doing so, then serve those images using a different method. Which is not at all recommended, will decrease performance and not tested by me.. emoticon

You can write a method which loads image content from local file and sends it to application. serveResource() method may be used, I guess. But for that you will need to change all urls to get resources by serveResource.. I don't know whether its possible but you can try..

David: is that really possible?

Will background-image property of css not help? check this http://www.w3schools.com/css/css_background.asp

Just place the image url at appropriate position. Suppose abc is the id of the element you want to set background of..

#abc{background-image:url('paper.gif');}
