Website design (iWeb)

I would like to create an e-commerce website using iWeb that includes customizable t-shirts from a user. In other words i would like to make it a possible for a customer to upload and image to be automatically attached to the t-shirt just like this link

Would like to know were i should start and how to do it if possible by using iWeb.

Using iWeb 09

Any ideas?

OwaziO, I think you’ll have to find a forum that specializes in iWeb design. A Google search of iWeb brings up a fair number on the first page of that search.
