Ti ho già fatto avere un esempio funzionante. Ne vuoi un altro, senza usare database? che produca una tabella? Eccolo:
codice:
<%@ Page Language="VB" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<script runat="server">
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs)
Dim p_img As String = RequestParams("p_img")
Dim p_max As String = RequestParams("p_max")
If p_img <> "" AndAlso p_max <> "" Then
ReturnImg(p_img, p_max)
End If
Dim a() As String = IO.Directory.GetFiles("C:\dati\Prove Nicon", "*.jpg", IO.SearchOption.TopDirectoryOnly)
Dim b(a.GetUpperBound(0)) As String
For i As Integer = 0 To a.Length - 1
b(i) = String.Format("[img][/img]", i, Path.GetFileName(a(i)))
Next
Me.DataList1.DataSource = b
Me.DataList1.DataBind()
End Sub
Private Sub ReturnImg(ByVal p_img As String, ByVal p_max As String)
Dim p_clip As String = RequestParams("p_clip")
If p_clip = "1" Then
Dim border As Integer = 4
Dim bmp As Bitmap = img.ImgLoad(p_img)
img.ImgClipSquare(bmp, CInt(p_max) - border - border)
img.ImgBorder(bmp, border, Color.White)
img.ImgSaveToResponseOutputStream(bmp)
Else
img.ImgResizeAndSaveToResponseOutputStream(p_img, CInt(p_max))
End If
End Sub

E' vero, lo ammetto, non sono bravo a spiegare: però ti ho dato una paginetta semplice, completa. Ti ho detto dove prendere la dll per fare le miniature, il codice javascript per ottenere l'effetto lightbox è reperibile qui:
