Struggling with terminology

[jennym]

Hi

I'm struggling with technical words I need to search what I'm looking for.

I want to create interactive pages for creating products, as an example, I'm using a coffee mug.

An image of a blank/white coffee is mug placed on the page, a website visitor uploads a design and the design is added to the mug. (eg Zazzle)

Can anyone please suggest some search words so I can find the software I'm looking for - or maybe someone knows the software?

Thanks for any help
