Digital portfolio for memorabilia?
 

I was wondering if anyone out there has come across a good way to create a digital portfolio for their memorabilia. I notice there are many apps that cater to card collectors such as CollX, LUDEX, etc, but I'm curious about what memorabilia collectors are doing?

I would like to create a portfolio of my collections, add some notes, organize them, and have the option to share my portfolio with others looking to trade.

Thanks for any insights you may have.
