I have an OsCommerce site using fantastico hosted on justhost.com.
My site currently looks like this www.luxedesignshoppe.com but I bought a template and need the template installed. This is the template I bought http://thischickdesigns.com/item_142/CAFE-MOCHA-SHELL.htm
I have the HTML codes and images but from what I understand, you will need to format them and install it.
Please read the template site for more details.
