How to add smarty variable for random number

How can I add some kind of variable for "theme system" that would change numbers randomly? The Idea is to change site's logo on start or reload. So, I need some variable <{random_number}> to put a number between 1 and 20 (for example) instead of <{random_number}> in the final page.
Hope you understood me

<{$xoops_banner}>

To get a random number between 1 and 20 inclusive, replace <{random_number}> with <{1|rand:20}>.

Can you assign this to a variable to reuse throughout the theme? (unless the random seed picked is the same for all refs in the theme).

If by "throughout the theme", you mean within theme.html and any files it includes:

 <{assign var='random' value=1|rand:20}> 
... 
A random value: <{$random}>

Cheers! I'm going to try and create a large header graphic, that'll be in 3 parts.
1) Header
2) Menu Bar Image
3) Ghost image at the top of the page contents.

So hopefully it'll look like a large continuous image that is nice and bold at the top but fades out in content.

I was toying with the idea of having different images per module, but think I'll use random instead. But will that play havoc with the page loading time...

Is there a way to use these variables in the syles.css sheet? I'm thinking random backgrounds for cells in tables.

I've put these in the style.css

 td#header1 {background-image: url(images/header1.gif);height: 155px;width: 775px;} 
td#header2 {background-image: url(images/header2.gif);height: 155px;width: 775px;} 
td#header3 {background-image: url(images/header3.gif);height: 155px;width: 775px;}

and the following in theme.html

<td align="left" id="header<{$random}>"><img src="<{$xoops_imageurl}>images/logo.gif" hspace="24" />td>

The theme is producing id="header1", id="header2" etc but the style isn't being shown.

Funny, that works today. I probably didn't refresh.
