Sub page_Load(Sender as object, e as EventArgs)

Const d as string="im/"

Dim s as string,html as string
Dim fullsizeimg as system.Drawing.Image
Dim dummyCallBack as System.Drawing.Image.GetThumbnailImageAbort
dummyCallBack=New system.drawing.image.GetThumbnailimageabort(AddressOf ThumbnailCallback)
Dim thumbnailimg as System.Drawing.Image
for each s in Directory.GetFiles(server.Mappath(d),"*.gif")

fullsizeimg=System.Drawing.Image.FromFile(s)
thumbnailimg=fullsizeimg.GetthumbnailImage(100,100,dummyCallBack,IntPtr.Zero)
thumbnailimg.Save(Response.OutputStream, ImageFormat.gif)
Next (s)

End sub

Function ThumbnailCallback() as Boolean
return False
end function
</script>

You are streaming an image to the browser which can only display one file at a time.

If you want a page full of thumbnails you need to implement a DataGrid or repeater of images.

e.g.

Code:

---

<asp:Repeater id="rptImages" runat="server">
        <ItemTemplate>
                <img src="createthumbnail.aspx?file=<%# DataBinder.Eval(Container.DataItem, "FileName") %>" />
        </ItemTemplate>
</asp:Repeater>

---

The createthumbnail.aspx page is passed a querystring of the file that needs to be made a thumbnail (using similar code to you posted).

All you need to do is create a list of files that are needed on the page and databind it to the repeater.

HTH - give me a shout if I have misunderstood what you are trying to do.
