Perhaps I can be a bit more extensive.
option 1) Image as backround.
This is very simple to do and there are a couple ways to do it.
technique 1: open your stylesheet and locate the reference to your menus. You will see a "backrground color : #123456" reference close by. Basically you want to end up like this
"background :
technique 2: open your style sheet and delete the "backround color : #123456" reference. save and close. open your theme.html and locate your
<td class="t_content_left"><img src="<{$xoops_imageurl}>images/pixel.gif" width="1" height="1" />td>
insert your image here. the problem with this method is that XOOPS is designed to flex. So if the dimensions of your left block needs to change then you will need to manually adjust the image size. otherwise, I believe that you will get a repeating image in the lb loop. However if thats what you are going for, then this is fantastic. Because you simply point this td reference to your image and it will treat it as the flex pixel. Just remember to adjust the size.
option 2) Show a background image everywhere except the left block loop.
very simple, its likely that in the stylesheet you have a reference to your left blocks background... "background color : transparent" <-- Change this to "background color : #123456" < simply define your hex.
However if you do not have a "background color :" then add one in.
All in all these should atleast give you an idea of where you need to be. play around with your settings. Worst that could happen is you'd learn.
