Need to alter the PHP script (Instagram API)

There is a ready script on PHP, which you can use to publish photos to instagram from your computer. But there's one piece of code is not relevant, namely the block of keys. These keys (the missing block) can be borrowed from another PHP script. Thus to modernize it. Then help to install it on a website that you can work through a web-interfeis. Write your terms and prices.
PS. here, as always, most of the messages from the mailing list. As spam. Therefore, these messages I'm ignoring. Write on the case.
