Thanks Alex, I understand and have no desire to break any rules. The college (where I work) communications team posts frequently to Instagram, perfect content for our several signage screens across campus.
What does “screen scraping” mean?
I found a free and easy-to-use widget called Feedgrabbr. That seems to provide close to what I was hoping for. I guess they host something on their site and do the java coding. I’m just a lowly desktop support guy, and have zero coding skills beyond basic HTML.
