Multi-image uploader for auction site

[katzrmine]

New to your forum here. Looking for help with the image uploader on my site.
I have been looking & searching for someone to help-fix-rescript a situation on my little auction website.This auction script only allows for one image upload. (whoever heard of a auction that only allows one picture of your item to sell ? I want to offer 4 uploads. I was told that it could not be changed by the person I got this auction from. And perhaps that is true, but I've never heard of a script that couldn't be changed IF you know what you are doing!! I've looked all over the cPanel & nothing appears to be anything I'm looking for to change. BUT I do not understand that part of a website. Do you?
The site is at Grannys Ice Auction
Do you have this knowledge?
Thanks for your time,
