Add Gift Registry Image Upload and Display Option to 3D Cart Ecommerce Site -- 2

We have an existing ecommerce website powered by 3D Cart. [login to view URL] For our Gift Registries section, we would like to add an input field that will allow the registrant to upload a photo of themselves (Bride and Groom for example) on the registry edit page, and then have the image shown on their actual registry page when viewed by customers. There is a place to host images on the site. I can pull any relevant html and css files from the ftp server. Or I can possibly look into getting you a limited login to view the necessary sections of the website admin interface to view/edit the html files. 3D Cart has an upload file feature as part of product options. I could create a dummy product with this feature and publish it if this would be helpful in analyzing the code and/or using part of it for this feature. This is a repost because the freelancer awarded the project did not agree to do it.
