uitableviewcell update

I have uitableview with cells.I download image asynchronous for each cell with ASIHttpRequest and put image into cell when it has been downloaded. Image downloads fine, but it puts when i click on cell, or scroll my uitableview. How to set image AND SHOW it immediatly?

    NSURL *photoURL = [NSURL URLWithString:urlString];
    __block ASIHTTPRequest *request = [ASIHTTPRequest requestWithURL:photoURL];
   [request setDownloadCache:[ASIDownloadCache sharedCache]];
   [request setCompletionBlock:^{       
   NSData *responseData = [request responseData];
   cell.imageView.image = [UIImage imageWithData:responseData];
    }];
   [request startAsynchronous];
      //other code (cell.textLabe.text = ...) etc.

Here are screenshots with cell before click on it, and after:
