buffering

I have several pages in which I show the user a target images and two additional images, and ask them to indicate which of the two images is more similar to the target image. After the answer the user is given the next similar page.

My problem is the time that the browser needs to show the images. It is not a smooth task - it is "flashy".

What I thought to do is create a page before the task in which i "show' all the images and then redirect to the task. However - it doesn't seem to  work. There is a way to make the task smoother?

The following code is the "buffer" page.

<%@LANGUAGE="VBSCRIPT" CODEPAGE="65001"%>

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<head>
<title></title>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
</head>

<body dir="rtl">
<p>please wait</p>

<%
Response.Buffer = True
response.write("<img src='small/b1.jpg'><br>")
response.write("<img src='small/b2.jpg'><br>")
response.write("<img src='small/b3.jpg'><br>")
response.write("<img src='small/b4.jpg'><br>")
response.write("<img src='small/b5.jpg'><br>")
response.write("<img src='small/b6.jpg'><br>")
response.write("<img src='small/b7.jpg'><br>")
response.write("<img src='small/b8.jpg'><br>")
response.write("<img src='small/b9.jpg'><br>")
response.write("<img src='small/b10.jpg'><br>")
response.write("<img src='small/b11.jpg'><br>")
response.write("<img src='small/b12.jpg'><br>")
response.write("<img src='small/t13.jpg'><br>")
response.write("<img src='small/t14.jpg'><br>")
response.write("<img src='small/t15.jpg'><br>")
response.write("<img src='small/t16.jpg'><br>")
response.write("<img src='small/t17.jpg'><br>")
response.write("<img src='small/t18.jpg'><br>")
response.write("<img src='small/t19.jpg'><br>")
response.write("<img src='small/t20.jpg'><br>")
response.write("<img src='small/t21.jpg'><br>")
response.write("<img src='small/t22.jpg'><br>")
response.write("<img src='small/t23.jpg'><br>")
response.write("<img src='small/t24.jpg'><br>")
response.redirect("task.asp")
%>
</body>
</html>

you can run a script before page redirect to stop the page for couple of seconds...
check below link about how to stop page redirect for say 5 second...

I'm sorry but that is not a "buffer page" because it all arrives in the browser as a plain old page with images.  You can "View Source" and see that.

It is possible to 'preload' images in javascript like they do in slideshows but even that doesn't completely change your problem because that counts on the first image being up there long enough to load the other images in the back ground.
