Are you using the latest version of Zen Cart? If so, download it from the addon section, extract, then just ftp the original to your site.

Of course, that assumes you didn't make changes before you added the image mod.

Your site took awhile to load. I am on a fairly fast connection and still got tired of waiting......

A few questions I have about your site....why do you have a checkout link in the header? I landed on your main page and for giggles, clicked that link and got an error message that my session expired.
Is there a reason the searchbox blends with the background? If I was to do a search, I wouldn't know where to type my inquery.

Site looks nice.
