Recreate thumbnails for existing images

Hi,

Our client requested bigger thumbnails for images shown in the media manager. We have a solution where bigger thumbnails are created for newly uploaded images and shown as 96x96 instead of 48x48. However all the images previously uploaded still have the existing thumbnail of 48x48 generated earlier resulting in an ugly preview. Is there a way to fire trigger the creation of a new thumbnail for an existing image?

Regards,

Have you tried ImageDescriptor attribute?

  public class ImageData : MediaData
  {
    /// <summary>
    /// Gets or sets the generated thumbnail for this media.
    /// </summary>
    [ImageDescriptor(Width = 96, Height = 96)]
    public override Blob Thumbnail
      {
        get { return base.Thumbnail; }
        set { base.Thumbnail = value; }
      }
  }

Yes I did both of these. However thumbnails are not regenerated when I run the job, when I look in the Azure storage explorer I still see the existing files.
