We need to keep it always in the last position.
If you want to add more items we need to insert them before this local source:

Items.Insert(Items.Count - 1, "New Items");

Try to add a local image source at the last position of the items source to display this extra item after populating data:

public ObservableCollection<string> Items { set; get; }
public MainViewModel()
{
    Items = new ObservableCollection<string>();

    // Add Data
    // Items.Add

    Items.Add("local image source");
}

Here is my simple template:

<CollectionView ItemsSource="{Binding Items}">
    <CollectionView.ItemsLayout>
        <GridItemsLayout Orientation="Vertical" Span="4"/>
    </CollectionView.ItemsLayout>
    <CollectionView.ItemTemplate>
        <DataTemplate>
            <StackLayout>
                <Image Source="{Binding}"/>
            </StackLayout>
        </DataTemplate>
    </CollectionView.ItemTemplate>
</CollectionView>

My point here is to display an extra cell with a local image at the last of the collection view.

        public MainViewModel()
        {
            Items = new ObservableCollection<ImageSource>();
        // Add Data
            // Items.Add
        Items.Add("local image source");
