ASP.NET SlideShowExtender retrieving images from web service, but doing nothing when executed

Go To StackoverFlow.com

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):

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