thumbnail bigger than original image

On the file upload you can get the thumbnail and resize it like so.

VB.NET:
Dim _orgThunbnail As System.Drawing.Image = System.Drawing.Image.FromStream(Request.Files("Thumbnail2_" & i).InputStream) ' used to hold the original image

'your fixed height and width
Dim thumb As New Bitmap(10, 10)

'Create a graphics object
Dim gr_dest As Graphics = Graphics.FromImage(thumb)

' just in case it's a transparent GIF force the bg to white if needed
Dim sb = New SolidBrush(System.Drawing.Color.White)
gr_dest.FillRectangle(sb, 0, 0, thumb.Width, thumb.Height)

'Re-draw the image to the specified height and width
gr_dest.DrawImage(_orgThunbnail, 0, 0, thumb.Width, thumb.Height)

'Save the image
_orgThunbnail.Save(Server.MapPath(upload_dir & newimagename & fileExt), originalimg.RawFormat)

I just wrote this code here and have not tested it, so it may need some tweaking if needed.
C# version

{
System.Drawing.Image _orgThunbnail = System.Drawing.Image.FromStream(Request.Files("Thumbnail2_" + i).InputStream);
// used to hold the original image

//your fixed height and width
Bitmap thumb = new Bitmap(10, 10);

//Create a graphics object
Graphics gr_dest = Graphics.FromImage(thumb);

// just in case it's a transparent GIF force the bg to white if needed
var sb = new SolidBrush(System.Drawing.Color.White);
gr_dest.FillRectangle(sb, 0, 0, thumb.Width, thumb.Height);

//Re-draw the image to the specified height and width
gr_dest.DrawImage(_orgThunbnail, 0, 0, thumb.Width, thumb.Height);

//Save the image
_orgThunbnail.Save(Server.MapPath(upload_dir + newimagename + fileExt), originalimg.RawFormat);
}
