Sorry for the very late reply, this wasn’t as high priority as other things so was left for a while.
I have the code in my <head> tags, just under wp_head(),
<?php if (is_category()) :
global $cat;
if ($cat == 42) :
?>
<style type="text/css">
#wrapper {background-image:url(http://streetwiseheadshop.co.uk/wp-content/themes/streetwise2/images/background2.jpg) !important;}
</style>
<?php
endif;
endif; ?>
Unfortunately that does absolutely nothing, no changes at all :/
