Very simple AJAX question

I have an online store catalog. On the page that displays all the category
items (like "Dresses") I have a ListView with an embedded DataPager, and all
this is wrapped with an AJAX UpdatePanel so the whole page doesn't have to
refresh to get the next page of items. Do I have to preload all the images
with client-side script on the initial load of the page, or is the handled
somehow through the UpdatePanel during subsequent async updates? My guess
is I have to load the pictures when the page initially loads....?

if(!IsPostBack && !ScriptManager1.IsInAsyncPostBack)
{
//add client-side script to preload ALL possible pictures for this
category
//of the catalog?
}

Thanks!

Hi Steven,

it would work without preload. If you have an Image control in
ListView, the UpdatePanel will manage updates.
 
Awesome, I'm assuming this would include an image button?
Thanks for your response.
