Hi Gerard,
I use real images on my site, but I switch them along with the CSS by
using PHP session variables to change the path to both images and css.
A link to an image will look like this:
<a href="somepage.php"><img src="<?php echo
$_SESSION['theme']?>/images/adlogo.jpg" />
A link to a style sheet looks similar:
<style type="text/css">@import "<?php echo
$_SESSION['theme']?>/css/default.css";</style>
The 'theme' setting is supplied by the user via a form. All of the
images and styles for the various themes are named exactly the same,
with the exception of their containing folder, which is named after the
color of the theme. Thus, when a theme is selected, I am ONLY changing
the name of the containing folder for images and css.
You can see how it works, and probably help me test it out as well. The
basic site is up now, though most of the themes are not finished, they
still need a lot of formatting changes and browser testing has not
started yet. Just a concept really, but if you like it I will give you
more details about how it works. See http://allegrodev.com for an
example. Good luck with your site.
Marshall
