mWebView = (WebView) findViewById(R.id.webview);
mWebView.getSettings().setAllowFileAccess(true);
mWebView.getSettings().setJavaScriptEnabled(true);
mWebView.getSettings().setBuiltInZoomControls(true);
String base = Environment.getExternalStorageDirectory().getAbsolutePath().toString();
String imagePath = "file://"+ base + "/test.jpg";
String html = "<html><head></head><body><img src=""+ imagePath + ""></body></html>";
mWebView.loadDataWithBaseURL("", html, "text/html","utf-8", "");

This did the trick as we have to append the"prefix "file://" before any file so as to display in the webview
