How to add multiple images in canvas (or grid) in WPF ?

if (imageFiles.Count() > 0)
            {
                foreach (string str in imageFiles)
                {
                    CreateATyhumbnail(str);

                }
            }

private void CreateATyhumbnail(string imagePath)
        {
            // Create an Image control  
            Image thumbnailImage = new Image();
           
            thumbnailImage.Width = 130;
            // Create a BitmapImage and sets its DecodePixelWidth and DecodePixelHeight  
            BitmapImage bmpImage = new BitmapImage();
            bmpImage.BeginInit();
            bmpImage.UriSource = new Uri(imagePath);
            
            bmpImage.DecodePixelWidth = 120;
            bmpImage.DecodePixelHeight = 120;
            bmpImage.EndInit();
            // Set Source property of Image  
            thumbnailImage.Source = bmpImage;
            
            imageGrid.Children.Add(thumbnailImage);
            thumbnailImage.Margin = new Thickness(15);
            //Canvas.SetLeft(thumbnailImage,130);
