Insert picture in crystal report at run time

Hi,
I am novice to vb.net and crystal report.I have path of image files stored in database.I want to display these images in detail section of my crystal report for vb.net using path as a parameter.I have no idea about how to do this.can u help me .if yes,Please write the code clearly for me.

I searched the net and found the following code but this didn't help me

Private Sub Section1_Format(ByVal pFormattingInfo As Object)


picture3.FormattedPicture = LoadPicture("D:\SourceCode\Banasthali_exam_system\Banasthali.jpg")

End Sub

Alternatively how to store picture as blob in databse and extract blob in crystal report.

I have the same problem but my code is in c#.
Can anyone help me?
