it's only generate rss feeds from an instagram user profile or hashtags. see this sample
that script fetch pictures from user profile and put each of them to rss feed item.
issue is the instagram add "?ig_cache_key=23456*" to each pic you upload to instagram . and result in rss feeds generated by instarss for pictures address was :
https://scontent.cdninstagram.com/t51.2885-15/e35/13712096_262107487501012_162919037_n.jpg?ig_cache_key=MTI5Njk2NDMzMzg2NzQyMDQ5MA%3D%3D.2
i want to change that script to auto remove "?ig_cache_key=*" from picture address in generated rss feed.
