This article explains how to load online images in the .NET MAUI AvatarView. To display an online image in the AvatarView, it is recommended to utilize the UriImageSource from the ImageSource and set the ContentType property to Custom. This allows for the use of custom images, including those sourced from the web.

<VerticalStackLayout
    Padding="30,0"
    Spacing="25">
    <core:SfAvatarView AvatarSize="ExtraLarge"
                       HeightRequest="200"
                       AvatarShape="Square"
                       ContentType="Custom"
                       Aspect="AspectFill">
        <core:SfAvatarView.ImageSource>
            <UriImageSource Uri="https://cdn.syncfusion.com/content/images/Images/Camtasia_Succinctly.png?v=22022017060923"/>
        </core:SfAvatarView.ImageSource>
    </core:SfAvatarView>
</VerticalStackLayout>
