Adding photos / videos in the "notes area" of each iphone contacts

To easily access the complete personal information including some extra photos / video in my iPhone contacts ( Ex: shop photo, product photo, or new product demonstration,... ), can I add extra photos / videos in the " Notes area " or " some other optional areas " of each personal contact ?

It will be easy for me to access complete information of each person when I open the App ( contacts ).

So I don't need to open another one or two App to get the complete personal information !

Thank you so much !
