[CB] Background image in post

[Wormopolis]

This code will allow you to put an image behind the text in a post. keep in mind that certain font colors dont look good when placed on a background of similar color.

I added in switches to control the background.
image repeating:
nr = no repeat
rx = repeat horiz only
ry = repeat vertically only

image position:
cx = center horiz
cy = center vertically
(you can use both together to put image in center of post)

simply type
[PBG:]URL OF IMAGE[/PBG:] into your post to add a background.

switches come right after [PBG: and before ]. like:
[PBG:nr,cx,cy]

seperate switches with commas. use lowercase for switches.

here is the code for global footer or board footer:


<script type="text/javascript">
