How to increase the speed of the scroll in the table view when images are being loaded in each cell?

Check out the last lines before [return cell]..After the images are being loaded the scrolling speed is decreasing..it seems the scroll gets stuck

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {

    static NSString *MyIdentifier = @"MyIdentifier";
    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:MyIdentifier];

    if (cell == nil) {
        cell = [[[UITableViewCell alloc] initWithFrame:CGRectZero reuseIdentifier:MyIdentifier] autorelease];
    }

    int storyIndex = [indexPath indexAtPosition: [indexPath length] - 1];
    NSString *itemDescription=[[stories objectAtIndex: storyIndex]
                                                 objectForKey:@"title"];

    CGRect aframe = CGRectMake(80, 30, 250, 40); 
    textLabel = [[UILabel alloc] initWithFrame:aframe];
        textLabel.font = [UIFont boldSystemFontOfSize:14];
    textLabel.numberOfLines=0;
    textLabel.textColor = [UIColor darkTextColor];
    textLabel.backgroundColor = [UIColor whiteColor];
    [cell.contentView addSubview:textLabel];
    textLabel.text=itemDescription;

    CGRect frame = CGRectMake(0, 0, 70,80);
    UIImageView *TopImageView = [[UIImageView alloc] init];
    [cell.contentView addSubview:TopImageView];
    TopImageView.frame=frame;

    m_strImage = [m_imglinkArray objectAtIndex:storyIndex]; 

    TopImage = [[UIImage alloc] initWithData:[NSData dataWithContentsOfURL:[NSURL URLWithString:m_strImage]]];
    TopImageView.image=TopImage;

    return cell;
}

Could you guys help me to increase the speed of the scroll?
