I am trying to display an image from a local assets directory on a ICS Android app.

The png is 40.png it's under appname\assets\40.png The string in string.xml is:

 <string name="p40"><img src="file:///android_asset/40.png"/></string>

And here is the code I use to load the IMG: 

              String myhtmlIMG= getResources().getString(R.string.p40);
              webView.loadData(myhtmlIMG,"text/html", null);

When I run with this I get an exception:

06-11 15:02:04.986: W/System.err(12939):    at libcore.net.http.AbstractHttpInputStream.checkNotClosed(AbstractHttpInputStream.java:68)
06-11 15:02:04.986: W/System.err(12939):    at libcore.net.http.FixedLengthInputStream.read(FixedLengthInputStream.java:41)
06-11 15:02:04.990: W/System.err(12939):    at java.io.InputStreamReader.read(InputStreamReader.java:244)
06-11 15:02:04.990: W/System.err(12939):    at java.io.BufferedReader.fillBuf(BufferedReader.java:130)
06-11 15:02:04.990: W/System.err(12939):    at java.io.BufferedReader.readLine(BufferedReader.java:354)

However if I was to make an html file in appname\assets\p40.html and include the same tags I would get the image. Problem is I must use dynamic png inserted into a html string so this is not a solution.

Is it my quote handling perhaps?

It's an escaping problem. Try using CDATA tags:

<string name="p40"><![CDATA[<img src="file:///android_asset/40.png"/>]]></string>

If the above doesn't work, escape everything and do Html.fromHTML()

<string name="p40">&lt;img src=\"file:///android_asset/40.png\"/&gt;</string>

Then

          String myhtmlIMG= Html.fromHtml(getResources().getString(R.string.p40));
          webView.loadData(myhtmlIMG,"text/html", null);

-edit- Just remembered the reason the image isn't loading. You have to override the webview load view to make it able to load from your asset folder. Code in this thread.
