Lazy loading image like tumblr on Android

On Tumblr, with the post have many images. They will be previewed by a local image. And then, when user click to, they will be replaced by real image. I want to do like that. I have a listview, each item as a post having a webview. I got html string, I replace src of img tag by local image. But I couldn't catch touching event on webview ( webview in listview)

            holder.webView.setOnTouchListener(new OnTouchListener() {

            @Override
            public boolean onTouch(View web, MotionEvent event) {
                // TODO Auto-generated method stub
                WebView.HitTestResult result = ((WebView)holder.webView).getHitTestResult();
                if (result == null) {
                    return false;
                }
                int type = result.getType();
                String extra = result.getExtra();


                return false;
            }
        });

result variable is always null ??? So the first question: how can I catch the event (touching in img in webview) ?

And then, the second question: How can I replace the touched img (local img) in webview by a real img ( I have the img url) ? Thank in advanced!

WebView.setOnTouchListener(new OnTouchListener() 
{
   public boolean onTouch(View v, MotionEvent event) {
   }
});
