This suggestion just in from member JPinBrooklyn:
And here's my answer:
The site host (Hoop.la) plans to roll out a Pinterest sharing feature (a link to pin at the bottom of each uploaded photo) in a next iteration of the site platform, though I don't know exactly when that will be.
In the meantime, you can pin any photo on this site as you would pin from any other site. I have installed a "Pin It" button in my browser that allows me to pin on any site I'm browsing (that allows pinning) at the click of a button. For instructions on how to install a "Pin It" button, please read this link on the Pinterest site.
Thanks for the suggestion.
