[gears-users] LocalServer - at the end of my rope; what am I doing wrong?

[KcBob_2000]

I can't seem to get this caching to work - I have read everything I
can find and have tried several things, but I must be missing
something basic.

I have an image and I am changing the src through a timer which works
fine, but when I take the page offline and clear the browser cache,
the images break so the LocalServer is not serving them up for some
reason...

Here is what I call from a button click:

 var localServer;
 var store;

function storeForOffline() {
                localServer =
google.gears.factory.create('beta.localserver');
                store = localServer.createManagedStore('test-store');
                store.manifestUrl = '/manifests/Patients.txt';
                store.onerror = onSyncError;
                store.oncomplete = onSyncComplete;
                store.onprogress = onSyncProgress;
                store.checkForUpdate();
            }

Timer code:

            var Nbr = 272;
            setTimeout("DoTimer()",2000);

            function DoTimer() {
                if (Nbr == 276)
                    Nbr = 272;

                document.images("ImgTest").src = "/Images/" +
Nbr.toString() + ".jpg";
                Nbr += 1;
                setTimeout("DoTimer()", 2000);
            }


Image markup:
 <img id="ImgTest" src="" width="40px" alt="" />

Manifest:

{
  "betaManifestVersion": 1,
   "version": "15",
   "entries": [
     { "url": "Default.htm"},
     { "url": "/Images/272.jpg"},
     { "url": "/Images/273.jpg"},
     { "url": "/Images/274.jpg"},
     { "url": "/Images/275.jpg"},
   ]
}

The images run fine even when I take the web server offline, but if I
call up another browser and clear the browser cache, the images break
which tells me the images are coming from the browsers cache instead
of LocalServer.  Where am I going wroing?
