Simple Technic to show loader when image is loading from url.

In xamarin forms when you assign UriImageSource as source to image control, IsLoading property value change base on current status. True for loading and false for complete loading process.

If binding method do not work for you for your xamarin forms image control, you can do this by programmatically.
For that you should subscribe PropertyChanged event of image control in xamarin forms.

Like this

Image x:Name="MyImage" PropertyChanged="OnPropetyChanged"


private void OnPropetyChanged(object sender, System.ComponentModel.PropertyChangedEventArgs e)
{
if (e.PropertyName.Equals("IsLoading"))
{
// put logic to show and hide your activity indicator
// myLoader.IsRunning = MyImage.IsLoading;
}
}
