I want to use the ASIHttprequest library to download some files, I am testing with their code and it is not working while the same code works on their sample

this is my code to call their view

> 
> QueueViewController
>  \*queueViewController = [[QueueViewController alloc]
>  initWithNibName:@"Queue" bundle:nil];
>  [self.view
>  addSubview:queueViewController.view];
> 
> 
> 

This the code to make the request

```
- (IBAction)fetchThreeImages:(id)sender
{
    [imageView1 setImage:nil];
    [imageView2 setImage:nil];
    [imageView3 setImage:nil];

    [networkQueue cancelAllOperations];
    [networkQueue setDownloadProgressDelegate:progressIndicator];
    [networkQueue setRequestDidFinishSelector:@selector(imageFetchComplete:)];
    [networkQueue setShowAccurateProgress:[accurateProgress isOn]];
    [networkQueue setDelegate:self];

    ASIHTTPRequest *request;
    request = [[[ASIHTTPRequest alloc] initWithURL:[NSURL URLWithString:@"http://allseeing-i.com/i/logo.png"]] autorelease];
    [networkQueue addOperation:request];

    request = [[[ASIHTTPRequest alloc] initWithURL:[NSURL URLWithString:@"http://allseeing-i.com/i/trailsnetwork.png"]] autorelease];
    [networkQueue addOperation:request];

    request = [[[ASIHTTPRequest alloc] initWithURL:[NSURL URLWithString:@"http://allseeing-i.com/i/sharedspace20.png"]] autorelease];
    [networkQueue addOperation:request];

    [networkQueue go];

}

- (void)imageFetchComplete:(ASIHTTPRequest *)request
{
    UIImage *img = [UIImage imageWithData:[request responseData]];
    if (img) {
        if ([imageView1 image]) {
            if ([imageView2 image]) {
                [imageView3 setImage:img];
            } else {
                [imageView2 setImage:img];
            }
        } else {
            [imageView1 setImage:img];
        }
    }
}

```

It looks like the queue is being setup properly but imageFetchComplete method is not being called when the download is done.
