So on my ASP.NET solution's default page, I have a SlideShowExtender object, linked to a WebMethod which retrieves slides from an MSSQL database. Through debugging I can confirm that Slide objects are successfully created from said database, but once the page has loaded the SlideShow element does nothing.
Below is my code; I appreciate in advance any responses received. Thank you.
Edit: I forgot to mention that I've have verified the integrity of the Image URLs; they're correct.
Default.aspx (Default.aspx.cs is just a standard code-behind with an empty Page_Load method):
<%@ Page Title="Home Page" Language="C#" MasterPageFile="~/Site.master" AutoEventWireup="true"

}
finally

if(read != null) read.Close();

Problem solved; I used jquery.cycle.all instead.
