Hopefully this might help
go into your theme.html
find
<table cellspacing="0"><tr>
<td width="whatever" background="whatever">
<{foreach item=block from=$xoops_lblocks}>
<{include file="/theme_blockleft.html"}>
<{/foreach}>
add a class instead of background color
<table cellspacing="0"><tr>
<td width="whatever" class="b1">
<{foreach item=block from=$xoops_lblocks}>
<{include file="/theme_blockleft.html"}>
<{/foreach}>
then add the class to the style.css file
.b1 { background-image:url('images/b1.jpg');
should work
well it seems to in " phpkaox" theme on my test sever
