document.body.style.backgroundImage = 'url('
+ (new Date()).getHours()
+ '.jpg)';

from 00:00 to 00:59 -0.jpg
from 01:00 to 01:59 -1.jpg
from 02:00 to 02:59 -2.jpg
....
from 23:00 to 23:59 -23.jpg

This code is preferrably placed in an onLoad-event of the body-tag.

Hope this helps,

Do you mean for the image to be loaded only with the page, and remain as
long as the page remains displayed, or do you want a new image to be
fetched each hour, in the manner of a clock? To get a good answer, a
good question is required.

It's a good idea to read the newsgroup c.l.j and its FAQ. See below.

At a given instant, you and I will see different images. If that is not
wanted, use getUTCHours().

How is that a bug? Firefox 3 is not an Update to Firefox 2.

Hi everyone,

In folder image i have 24 pictures, and i would like to have some

Have you considered changing the image on the server? Every hour you
could replace say 'background.jpg' with a copy of a different image,
also called 'background.jpg'.

Better use dedicated 404.asp for that:

<%
qstr = lcase(Request.ServerVariables("QUERY_STRING"))
if right(qstr,15)="/background.jpg" then
response.redirect "/myDir/myHourPic" & hours(now) & ".jpg"
end if
%>
You have reached my 404 page.

Or just do:

<img src='mySwitchingJpg.asp'>

=========== mySwitchingJpg.asp ============
<% 'vbs
Response.Expires = -100
response.redirect "/myDir/myHourPic" & hours(now) & ".jpg"
%>
===========================================

sorry vbs, OT.
