How do I save images in database

VB

Am trying to insert an image into database table called Picture.

When I try to insert a (.png) image, I get no error but when I try to insert a (.jpeg) image or others apart from (.png) then I get this error
"A generic error occurred in GDI+".

This is my code

What I have tried:

btnsave ()

Try

Dim mstream as New System.IO.MemoryStream ()
PictureBox1.Image.Save(mstream, System. Drawing.Imaging.ImageFormat.Jpeg)
Dim arrImage() As Byte = mstream. GetBuffer()

sql = " Insert into Picture (Pic) & _
"Values(@pic)"

Connect()
cmd = new OledbCommand (sql,conn)

cmd.parameters.Addwithvalue("pic", arrImage)
 cmd.ExecuteNonQuery()

Catch ex As Exception 
MsgBox (ex.Message)

End Try
End Sub
