How to display last photos from Instagram on your site
Problem with Instagram is that doesn’t support any simple interface for user posts like some simple XML of RSS feed which could be easily processed.
Yes, we can use Instagram API, but this solution is very complex and unnecessarily complicated.
After the authorization Followgram retrieves your photos and lets you use the RSS feed for these photos.
We can use the feed at: http://followgram.me/user/rss
Now you can process this feed and display photographs, like this:
