ASP.NET Web Api End Points for server manipulation of the pictures

This is a web api implementation.
For changing the crop and size of images it uses ImageProcessor .NET and
Newtonsoft.JSON.
These can be installed in your VS project by Nuget
PM> Install-Package ImageProcessor
PM> Install-Package Newtonsoft.Json

Good luck!

NOTE: I didnt actually test the file after replacing my custom code with
some dummy paths.
