Prestashop 1.6 - product customization

[taka10]

Hello,

I just installed a site for prestashop 1.6 sales cakes customizable .

I love that the customer can , at the time of the order, just after step delivery, customize cake by sending a text or picture.

The image and / or text will be sent in the mail order and we can find the information from the administration.

Can you guide me in developing this addition (I have attached an example to illustrate my explanations).

Thank you in advance
