1- If you want to resize the image just for display then you can set the width and height of the image as required. 2- If you want it be interactive, so that client can resize the image then I will prefer some jquery plugin to do this task. Check this out http://plugins.jquery.com/taxonomy/term/2532[^] 3- If you want to do this at server side then using the GDI+ you can resize the image. Check this Resizing a Photographic image with GDI+ for .NET[^]

Then explore the 3rd option, you will find some example in the article which scales the image by fixed size of percentage.

This Function Can help you! :-D

Public Function ResizePicture(ByVal sourceImage As Bitmap, ByVal newSize As Size) As Bitmap

    Dim Result\_image As New Bitmap(sourceImage, newSize.Width, newSize.Height)
    Dim Gr As Graphics

    Gr = Graphics.FromImage(Result\_image)
    Gr.DrawImage(Result\_image, 0, 0, newSize.Width, newSize.Height)
    Gr.Save()

    Return Result\_image
End Function

Then you can save the output of this Function By using ResizePicture(MyBitmap, New Size(100, 100)).Save(MapPath("/") & "/Images/MyImage.png", Imaging.ImageFormat.Png) Note: These codes are in VB.NET Language, but you can simply convert it to C# or any .NET language
