Can't resize image files proportionally.

[JimboD]

Hi all I have a form on my site that my visitors use to upload pictures that are used on another page. The pictures are sent to an image file and the pic name is stored on a Access database. I have the pictures (5 of them) uploading and sent to the DB and file and all works fine. The only problem is that sometimes the pictures are distorted or way to big. I need to be able to re size them proportionally based on the width. I have tryed a bunch of things and had no luck. I have a set of radio buttons and a bunch of other stuf on the page but I cant seam to be able to figure out what the code to do this is and where to put it. Below is the code I have that works.
Can anybody help me?

Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
'Put user code to initialize the page here
If Not IsPostBack Then
getconfiguration()
End If

Pic1.ImageUrl = url & "\images\" & saveimage1
Image1.ImageUrl = url & "\images\" & saveimage1
Image2.ImageUrl = url & "\images\" & saveimage2
Image3.ImageUrl = url & "\images\" & saveimage3
Image4.ImageUrl = url & "\images\" & saveimage4
Image5.ImageUrl = url & "\images\" & saveimage5

End Sub
Private Sub getconfiguration()
