Customized-Product Preview -- Is This Possible?

I am seeking a shopping cart solution for my client, who creates items which are personalized with a customer supplied image. While the base costs are not customized, I wondered if Zencart might have a solution for people who want to offer customized products, and allow customers to preview what the item might look like by uploading an image and being able to move and/or crop the image to get the best design possible for said custom product.

I see someone has written a commercial addon for Magento so Im hoping someone on here might point me to a simillar product:

Looks like there is a previous thread on this in the Zencart forums but its outdated and was never answered:

Can anyone help?

I have not seen a module for this contributed but there are hundreds

I suspect that this would require a good amount of custom code to effect

Yeah. I have seen it on many sites, usually in Flash or AJAX form, and they appear to be independant from any CMF/CMS that the entire site is built on. So, to be fair, I admit this may not be a Zecart question. I just hoped that there was a zencarter who had created an add-on to get the best integration possible. Still, Im open to finding a site that sells the Flash app which produces the ability to preview your customization.
