I assume that the data has been read into a dataset!
To read an sql blob field into a picture box, just do this:
Dim pic As New PictureBox
Dim img As Byte() = rs.ImageContent.ToArray
Dim ms As New MemoryStream()
ms.Write(img, 0, rs.ImageContent.Length)
.Image = Image.FromStream(ms)
I hope it's use full
