bellow method done your need:-

 - (void)viewDidLoad
    {
        [super viewDidLoad];
    // Do any additional setup after loading the view, typically from a nib.
    NSURL *url = [NSURL URLWithString:@"yourimageurl"];
    NSURLRequest *req = [NSURLRequest requestWithURL:url];
    [webV loadRequest:req];

    UITapGestureRecognizer *gs = [[UITapGestureRecognizer alloc] init];
    gs.numberOfTapsRequired = 1;
    gs.delegate = self;
    [self.view addGestureRecognizer:gs];
    }


-(BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldReceiveTouch:(UITouch *)touch {
    NSLog(@"TAPPED");
    //Touch gestures below top bar should not make the page turn.
    //EDITED Check for only Tap here instead.
    if ([gestureRecognizer isKindOfClass:[UITapGestureRecognizer class]]) {
        CGPoint touchPoint = [touch locationInView:self.view];

        NSUserDefaults * userDefaults = [NSUserDefaults standardUserDefaults];
        bool pageFlag = [userDefaults boolForKey:@"pageDirectionRTLFlag"];
        NSLog(@"pageFlag tapbtnRight %d", pageFlag);

        if(self.interfaceOrientation==UIInterfaceOrientationPortrait||self.interfaceOrientation==UIInterfaceOrientationPortraitUpsideDown) {
            NSString *imgURL = [NSString stringWithFormat:@"document.elementFromPoint(%f, %f).src", touchPoint.x, touchPoint.y];
            NSString *urlToSave = [webV stringByEvaluatingJavaScriptFromString:imgURL];
            NSLog(@"urlToSave :%@",urlToSave);
            NSURL * imageURL = [NSURL URLWithString:urlToSave];
            NSData * imageData = [NSData dataWithContentsOfURL:imageURL];
            UIImage * image = [UIImage imageWithData:imageData];
            imgView.image = image;
        }
    }
    return YES;
}
