infobox color changes easier

There are two scripts here:
generate_corners.php
corner.php

generate corners.php is a simple script to generate the corners. Put it in the images/infobox directory and make it writable by the web server then point at it. It will create the three infobox corner files in png (or gif if you have that compiled in) from the #rrbbgg color and show you the results. When pointed at it will guide you through.

corners.php is a dynamic replacement for the corner images. Unfortunately, it's just an example. The dynamics of it are mediocre, because the color is a simple php definition rather than pulling from a database. However, pulling from a database wouldn't make sense unless stylesheet.css did also.

Info for corner.php:

This is a simple replacement for those images. Takes arguments like so:
corner.php&l=l == corner_left.gif
corner.php&l=r == corner_right.gif
corner.php&l=rl == corner_right_left.gif

anything else is like rl

At the moment the color needs to be changed by hand, but I can only see two possible options (parsing the css in the corner.php would be difficult):

-php stylesheet with flat file defining colors
-php stylesheet with colors coming from sql
this could be rough on a database because css is called a lot

If the stylesheet were php then you could have the admin module change the colors pretty easily. You could also maintain themes for customers a bit easier.
