I'm developing a web application, and my client asked me about Facebook images appearing in his application, in some area of the site, with the desired hashtag .
Example, he will cover a certain example, his clients take photos and post them on Facebook with the hashtag #
#EventoDoFulano , and these photos are displayed on his website.
I'm developing this application using ASP.NET MVC 5, with jQuery in frontend. But solutions are welcome on Web Forms too.
I think you can do it using the GRAPH API.
