Hello, from what you described it almost sounds like what you are looking for and or should be focusing on delivering is an app that plugs into social media to retrieve the image and alter it as you want. By changing or re-thinking your business model (if you have one) you may be able to offer your product this way through a 'free app' with either in-app purchase options or monetizing else wise such as through ads.
