Suggestions for Image focussed view

I'm asking what UI toolbox should I use to display Large Images on a vertically scrolling view and overlay buttons such as like dislikes over the image. I'm currently using UITableViewController and within it's UITableViewCell cell's source I add the image as

           var imageView = new UIImageView();
            imageView.SetImage(url : new NSUrl(Uri.EscapeUriString(imageURL)));
            imageView.Frame = new RectangleF(0, 0, 320, 320);

I also override the GetHeightForRow to give the height I want as

        public override float GetHeightForRow(UITableView tableView, NSIndexPath indexPath)
        {
            return (float)320.0;
        }

It displays fine however I'm looking on suggestions on how to overlay buttons and display buttons/labels over it and also below it inside the same cell. I hope to bring the user to same view with comments displays whenever they tap the image and be able to write. Something like below,

Thanks in Advance. I'm just looking what widgets should I look into and how should I go on about implementing it.
