You can use Sitecore.Data.Fields.ImageField class to update an Image field. For example, to update the Image field named ImageField in the /Sitecore/Content/Home item in the Master database to the /Sitecore/Media Library/Images/Sample image:

Sitecore.Data.Database master = Sitecore.Configuration.Factory.GetDatabase("master");

Sitecore.Data.Items.Item home = master.GetItem("/sitecore/content/home");

Sitecore.Data.Items.Item sampleItem =

master.GetItem("/sitecore/media library/images/sample");

Sitecore.Data.Items.MediaItem sampleMedia =

new Sitecore.Data.Items.MediaItem(sampleItem);

Sitecore.Data.Fields.ImageField imageField = home.Fields["imagefield"];

if (imageField.MediaID != sampleMedia.ID) {

    home.Editing.BeginEdit();
    imageField.Clear();
    imageField.MediaID = sampleMedia.ID;

    if (!String.IsNullOrEmpty(sampleMedia.Alt))
    {
        imageField.Alt = sampleMedia.Alt;
    }
    else
    {
        imageField.Alt = sampleMedia.DisplayName;
    }

    home.Editing.EndEdit();
}

  • The setting name “AllowDuplicateItemNamesOnSameLevel” is in Sitecore.config file under App_Config folder. Set it to false to restrict the duplication then try.
