I want to make a api for image saving on signup so how can i make api to save my images or gearhost server or cloud ?
You should program this using the Microsoft ASP.NET Framework. Or you could try to find someone else’s source code that does this functionality and customize it to your liking. Do you know how to program web apps? If not there are a ton of resources for beginners. Let me know if you need links to anything in particular.
