                    <Image.GestureRecognizers>
                        <!--<TapGestureRecognizer Tapped="OnTapGestureReconizerTapped" NumberOfTapsRequired="1"></TapGestureRecognizer>-->
                    </Image.GestureRecognizers>
                </Image>

            </StackLayout>

        </Grid>
    </ContentPage.Content>

the first image is loaded correctly, but others images don't load. Only the first image is shown. I did many attempts and i didn't get success.
