Answer 1

I changed my code a little bet and got not that much file_get_contents.
But i found out that the Instagram API is really slow. So if i integrate the
instagram API my page loaded really slow. If i use Jquery Code it works fast but, everyone can look into the code and see the script brackets and thats what i dont want.
