xamarin forms dynamic image tapgesture recognizer control

hi,
How can I provide control (change) of my dynamic images created in xamarin forms by clicking .
sample ;
Image ggImage = new Image(); ggImage.Source = otoTip.imagex; ggImage.AutomationId = "seat_" +otoTip.num; ggImage.WidthRequest = imageWidth; ggImage.HeightRequest = 50; ggImage.VerticalOptions = LayoutOptions.Start; ggImage.HorizontalOptions = LayoutOptions.Start;

ggImage.GestureRecognizers.Add(tapGestureRecognizer);
for example, I just want to change a resume source
