Not too hard, the plumbing would be just having <IMG> tag or <asp:Image> in DataGrid's ItemTemplate and its src or ImageUrl attribute points to the URL to that handler/page. That's how it works because external resources (such as images) need to fetched with separate HTTP request from the HTML/markup itself.

E.g. You link to the custom page /hander which processes the request and generates the image from given parameters, from <IMG> / Image control.

Thanx for reply,
My code is
---------------------------
Dim a As Image
Dim thum As Image
Dim path As String
path = Server.MapPath("1.jpg")
a = a.FromFile(path)
thum = a.GetThumbnailImage(50, 50, Nothing, IntPtr.Zero)
thum.Save(Response.OutputStream, ImageFormat.Jpeg)
-------------------------------------------
so how can i pass " thum.Save(Response.OutputStream, ImageFormat.Jpeg)" in Image control -> Image URL property...,
plz give any sample code(Prefere in VB.NET), this is my great help, ....
Thanx Once again
Sajjad

If that given code runs on imagegenerator.aspx without any querystring parameters given to the URL

It would be

<asp:TemplateColumn>
   <ItemTemplate>
      <asp:Image ID="image" runat="server" ImageUrl="imagegenerator.aspx" />
    </ItemTemplate>
</asp:TemplateColumn>

E.g as I explained on previous post, due to working of HTTP, the page where IMG tag resides fetches it from the given page (fetching actually happens by the browser, with separate requests, one for each image)

Thanx for reply,
I try it, but it not working......,its headache for me.....
plz write the code for this, if u don't mind...
I wanna generate Thumbnail on Runtime, but it not store in harddisk or Database,and show in Image Control which are in data grid....
I can't under stand the Scenrio which are u give, because when Thumbnail generate by this command :
thum = a.GetThumbnailImage(50, 50, Nothing, IntPtr.Zero)

then how can i set the Image URL property of Image control to Thum.....
plz help
thanx Once again...

You need this resizing module... GetThumbnailImage has issues... And you'll need managed disk caching for performance reasons...
