Constant Content

I've been having a problem when ever I try to submit this illustration 'Corellian Reserve'. At first I thought it my be the switching between servers but now I just tried again and it still won't work. This is the message I get when I click 'submit files'


Fatal error: Call to undefined function imageSX() in /home/constant/public_html/components/inc/functions.inc.php on line 1185

Is there something wrong on my part or is this an internal error.

Thanks for any help.
