Display an image in a ListView

Question

Hello, I have a Prestashop database and an app that connects to it. With queries, I can display the data on images for example, but I would like to display the image instead of the data. I have defined a ListView there to display the results but only the image information is saved in the database.

My Recherche.xaml.cs

private void VoirImages(object sender, EventArgs e)  
        {  
            if (afficherImages.Text == "Voir les images")  
            {  
                cn = new MySqlConnection("***************");  
                try  
                {  
                    if (cn.State == System.Data.ConnectionState.Closed) { cn.Open(); }  
                    DisplayAlert("Infos:", "Vous êtes connecté", "ok");  
                    afficherImages.Text = "Se déconnecter";  
                    Connecté = true;  
                    imagesbdd.IsVisible = true;  
                    produitsbdd.IsVisible = false;  
                    tracteursbdd.IsVisible = false;  
                    requettebdd.IsVisible = false;  
  
                    {  
                        if (Connecté)  
                        {  
                            MySqlCommand cmd = new MySqlCommand("SELECT * FROM ps_image_lang WHERE id_image = 24192", cn);  
                            using (MySqlDataReader Lire = cmd.ExecuteReader())  
                            {  
                                var data = new List<Image>();  
                                while (Lire.Read())  
                                {  
                                    string id_image = Lire["id_image"].ToString();  
                                    string id_lang = Lire["id_lang"].ToString();  
                                    string legend = Lire["legend"].ToString();  
                                    data.Add(new Image(id_image,id_lang ,legend));  
                                }  
                                imagesbdd.ItemsSource = data;  
                            }  
                        }  
                        else  
                        {  
                            DisplayAlert("Infos:", "Plantage", "Ok");  
                        }  
                    }  
                }  
                catch (Exception exp) { DisplayAlert("Info:", "Plantage", "ok"); }  
            }  
            else  
            {  
                cn.Close();  
                DisplayAlert("Infos:", "Vous êtes déconnecté", "ok");  
                afficherImages.Text = "Voir les images";  
                imagesbdd.IsVisible = false;  
                produitsbdd.IsVisible = false;  
                tracteursbdd.IsVisible = false;  
                requettebdd.IsVisible = false;  
            }  
        }  

My Recherche.xaml

<ListView x:Name="imagesbdd"  
                      IsVisible="false"  
                      SeparatorColor="DeepSkyBlue"  
                      HorizontalScrollBarVisibility="Always"  
                      HorizontalOptions="Start"  
                      VerticalOptions="Start">  
                <ListView.ItemsSource>  
                    <x:Array Type="{x:Type x:String}">  
                        <x:String>Liste des images</x:String>  
                    </x:Array>  
                </ListView.ItemsSource>  
            </ListView>  

My Image.cs

namespace TractoApp.Data  
{  
    class Image  
    {  
        public string id_image;  
        public string id_lang;  
        public string legend;  
  
        public string Id_image()  
        {  
            return id_image;  
        }  
        public string Id_lang()  
        {  
            return id_lang;  
        }  
        public string Legend ()  
        {  
            return legend;  
        }  
  
        public Image(string id_image, string id_lang, string legend)  
        {  
            this.id_image = id_image;  
            this.id_lang = id_lang;  
            this.legend = legend;  
        }  
        public override string ToString()  
        {  
            return "N° " + id_image  + " - " + legend;  
        }  
    }  
  
}  

How can I convert the id to the address of the image to display it?
