No problem. It was actually your advertisement script. You had it at the very top of the code, so my plugin found it's search string inside of your advertisement code.
Open vbulletin_fireworks.js and replace the red number (pretty much all of the number 1s) in the following code with how big you would like it. Keep in mind that the bigger it is, the more they become squares. They are pixels after all and pixels are squares.
Code:
